Subject: [Caml-list] Unreliable Threading?
Ealier, when developing a mixed C/C++ and OCaml program, it looked as
thought the OCaml threading code was "unreliable" in that I would get
crashes under the MSVC++ debugger of "Invalid Handle" errors. But running
the code outside of the debugger works just fine.

I now believe the problem has nothing to do with OCaml or its threading
code, but rather the way the M$ debugger attempts to walk stack frames
looking for contexts to report. Since OCaml threading does its own thing, M$
appears to get lost in this process and ends up crashing on its own --
incorrectly attributing the error to the code under test.

All efforts to use OCaml multithreading and Channels for inter-thread
coordination HAVE been quite reliable outside of the M$ development
environment.
