 I've been unable to reproduce the crash on x86 (tried with smp
 hardware too) so I've been examining the code to try and spot the
 smoking gun.  mono_pthread_key_for_tls () is only called from mini-ppc.c.
 When you produced the backtrace, were there any other threads running?

+No, this is on x86, on a single CPU system (my thinkpad).  Those were
+the only two threads in my backtrace.
+This crash is very sensitive to timing -- trivial perturbations of my
+code (i.e. adding and removing Console.WriteLines) cause it to appear
+and disappear, and change its frequency.  I'll try to put together a
+simple example that reliably reproduces it.
