I think one solution for third party libs for now is to use dlsym() to
bind to the pthreads symbols... that way if it's being run from outside
Wine, the call will fail and it knows to dlopen libpthreads first before
continuing, and if Wine is already linked in then dlsym() will pull them
from the global symbol table and the housekeeping gets done. It takes a
bit of extra effort, and obviously you need to patch the libraries, but
it's nothing terrible.
