dlopen in multi-threading environnement

Hi,

It looks like threads can't make dlopen at the same time...

Is that true?

I tried googling for `dlopen thread safety', no luck. I found an interesting link, though: http://gcc.gnu.org/ml/java/2001-10/msg00107.html (beware of the date).

In any case, I find it likely that dlopen need to mutex something (kernel vmem tables? Loading a symtab into ram?).

I haven't investigated it thoroughly, so I don't know--but whatever the case may be, you can always just

Code:

def my_dlopen(foo):

    mutex.lock()

    library_dlopen(foo)

    mutex.unlock()
