:)

Though it shouldn't have been necessary, but I saw situations where it 
was as well.

I think it did send alerts about running low on disk space (or memory), 
even if it would automatically reclaim the space if required.

Print queues were usually really bad for that, if the person who built 
the server forgot to flag the directory "immediate delete".

Disk space, probably, and in 2.x or 3.10 that may have been the case.

I think post-3.10, the queue directories were automatically flagged 
"purge immediate".

Directory handles.

It came back to me in the shower.

Ah, yes, that would have changed certainly in 4.0, but a lot of things 
changed in the disk subsystem in 4.0. (compression, block suballocation, 
now that I think about it, HFS/migration might've been introduced at that 
point, too).

Maybe I'll find an engineer who worked on it next week at BrainShare. :)
