I see. The hard requirement is that when mono code is executing, the
stack in use must be for a thread which is known to libgc, so it gets
a full view of the root set during collection.
In theory everything would work correctly if a call into Mono thunked
into another thread created by the Mono runtime/libgc thread
calls. This seems somehow safer anyhow.
I wonder if the Native Posix Thread Library in RedHat 9 does anything
to make this easier:
