Our production Rails environment has been having some memory problems 
for a while.  Once a week or our mongrel daemons swell in memory usage 
and it pushes beyond what our box can comfortably handle.  We're hunting 
for the root cause, but a simple restart of the mongrel processes clears 
it up for another week or so.

We installed the smartleaf patched ruby on our production environment on 
Monday.  Since that time we had our processes balloon at least a dozen 
times in two days.  After reverting the patch to ruby it has returned to 
normal.  I don't know if our situation is a corner case or not.  I'm 
just wanting to let folks know who are trying to decide what to do that 
we've had problems with the smartleaf patch.
