I wonder if this is related to the problem I'm seeing, which seems to 
cause ruby to slow down after many calls to gets.

I've confirmed that the slowdown I'm seeing has existed in the trunk 
ever since YARV was merged, though I don't know at what point in YARV 
development the problem first appeared.

I also have an example where I'm not seeing a slowdown.  The most 
striking difference seems to be that my desktop (which exhibits the 
slowdown) is a dual Xeon running an SMP kernel, whereas my laptop (where 
YARV runs as fast as 1.8) is a single-CPU Pentium 4.

Are there any known incompatibilities between YARV and SMP?

Paul
