If you're going to use the computer for other stuff during the render,
setting POV-Ray to lower priority ensures that other applications remain
responsive. If the computer is left alone during rendering, it doesn't
matter what priority it runs at.

Nope. I'd hate to see my computer frozen because
the task runs at the highest possible priority. Just a
sensible precaution. If your computer is idle, PovRay
gets all the CPU anyway. If you use your computer,
you don't feel like you're using a 486.

For heavy renders - Linux rulez (and other unix family systems probably).
Stability, memory managment, remote access.

While I understand "remote access" issue (which of course has helpers like
SMPOV), I wonder what "stability" or "memory management" in non-linux releases
of POV-Ray are you addressing here.

It would be more easy (and cheaper) to install Linux on 64 bit processor to
access > 4 GB of memory.
Linux has much better memory/swap managment, if You have two phisical HDDs,
You can put them on different HDD controllers and create swap partition on
both, and configure system to interlace swap between both drivers with
would create something like RAID array for SWAP and increase performace up
to 50% (especialy on serial ATA or better SCASII drivers).

Actually, it (RAID 0) will gain little to nothing for a swap partition
because what matters for a swap partition is the seek time of the disk it is
on. It certainly will not gain anywhere near 50%. More like 5% if you are
really lucky.
Only is you need plenty of read and write disk access for large blocks of
data (i.e. a server or video storage for editing) you will benefit from RAID
0. Or if you need to store very large data sets and have no other means to
create a single partition (very unlikely these days). And even then you
would probably not use RAID 0, but rather RAID 1 or more likely RAID 5.

Or - huge meshes, photons data, media data (df3) etc.
I dont say its a common purpose :)
And linux realy is a stable OS (compared to i.e. Windows98,Me) none my
linux-computeres had crashed (for over half year of using).

Half year? As far as I remember my Windows 95 did not crashed for 5 years until
I did not changed my machine to XP which did not crashed since buying (November)
too. My WinNT4 at work did not crashed since 6 years when I recived it. IMO it's
up to hygiene of taking care about your OS, about installing new unknown
software, blind changing registers, using wrong drivers, using noname hardware
etc. etc. Alltogether I consider Windows stable for POV-Ray use. Note that I'm
software developer who needs from time to time kill applications, but it never
caused OS crash.

Hmm - this is highly subjective it seems. I have crashed NT4 four times in
an hour once trying to install IBM NetCommerce...

Obviously. I was talking about my experience with Windowses. Perhaps I was lucky
but I have mainly good memories :-)

It must be one of those noname products I was refering because I do not see it
in http://www.ibm.com/products/az/ ;-)
Anyway if it did not crashed under POV-Ray it doesn't change fact that stability
of Windowses for POV-Ray related production is at least good :-)
