We keep a hash of all of the Ruby objects we've ever referenced from =
.NET.  It is pretty low-tech, but works to keep the GC from harvesting =
the objects.  (We actually never release them - proper GC is something =
we still need to work on.)

This may not have been in any version that you have - there are some =
Ruby-in-.NET improvements in our R3 release (due soon).

That sounds like it could be the case - I hope you find the problem!  If =
you want to bounce any other ideas off us - just send them ...
