OK, using the modified beta 30, render times for 800x600 w/ no AA are:

2 Threads: 79 seconds
1 Thread: 33 seconds.

The top 50% of the render completes in 17 seconds using either 1 or 2
threads, so something is odd there, but most of the problem is in the
lower half.

...

OK, some further testing revealed the main problem.

In the file lsl_legends-symbols.inc, try commenting out the code
beginning with:
text {
	ttf "arialbd.ttf",
	"NOMINAL",

And ending with:

#end  // SKIP PREVIOUS YEAR IF MONTH GRAPH
object {
	MinimalCurve
	translate <0,-6*52,-15>
}
translate 0.5*z
}


This makes the file render in 9 seconds with one thread, and 6 seconds
with two - which I would call a return to normalcy :)

Now, the next task is to come up with a simpler demonstration of the
problem.
