Ah ha. 

I was going to say that Xitami didn't use threads, so I didn't see what
the problem could be, but IIRC there are a few minor uses of threads for
various auxillary things (and EMX uses threads for a few things).
(Xitami mostly works as a single process, single thread, and uses
select() and SMT to figure out what to do next.)

Our development version makes even less use of thread-related things, so
it's possible the problem might go away with that.  Unfortunately we
don't curerntly have an OS/2 development system, let alone a SMP-capable
OS/2 development system available.  However I do have a SMP Linux
development system, and I might try playing there and see if anything
breaks.

And it's useful to know that single-threaded Xitami is very stable. 

Thanks for following this up.
