[M3devel] AMD64_FREEBSD problems with current RC from m3 site

[Mika Nystrom]

Hello m3devel,

I'm running into problems with the current release candidate.
I'm attaching a backtrace from one crash, but I think I also am seeing
deadlocks in the threading system---my application goes catatonic.
Of course it *is* possible it's a bug in my application, but it works
on PM3 and on CM3 on PPC_DARWIN.

Finally I'm still concerned about threading performance but in the light
of the bugs it's hard to say much about it yet, I think...

(The program in question is a highly multithreaded stock market
simulator.)
