Which in hindsight, sounds a lot like that bug 162 linked above - the libX11
xlib_ctor would call XInitThreads() at library load time, which would use the
stubs to fake initializing the mutexes, and then libxcb would be loaded later
(likely when XOpenDisplay() is called) pulling in the real pthreads library,
Why is libxcb only loaded later? I would expect that by the time XInitThreads()
can be called, the dynamic linker has at least loaded all dependent libraries.
So, if libxcb links against libpthread, then libpthread should already be loaded
at this time.
Is this thinking wrong?
I'm not familiar with the runtime linkers on all platforms, but I know at least
on Solaris, lazy loading won't load the library until the first reference to it
is made (or a search needs to be made for a reference that doesn't have direct
binding information to record what library to load for it).
I also don't know if the ordering between library loading and init section
execution is well defined.
