Re: 1.6 and pthreads [Re: Why doesn't gh_enter() return?]

[Alejandro Forero Cuervo]

    nothing prevents you from using Guile in a pthread application,
    provided that you call into Guile from no more than one thread
    simultaneously.  

Simultaneously?

Does this mean I can just add a mutex around the Guile-calling code
and just forget about it?  I mean, it doesn't matter if all threads do
call functions in Guile, as long as they don't call them
simultaneously, right?  Or am I misunderstanding you and do you really
mean only one given thread can call functions from Guile, that if a
given thread calls functions in Guile, no other threads can do it?
Hmm, I really don't know about its internals, but having multiple
stacks must make things hard for Guile's garbage collector.

Btw, gh_eval and gh_eval_str are reentrant, right?  If I call gh_eval,
and it happens to call my C code, I am allowed to call gh_eval there,
right?  If so, are any functions there not reentrant?

Any plans of making it possible to call it from multiple threads
simultaneously?  I'm afraid that would be required for my pthreaded
application server... :/

Thanks.
