No, it was dynamic LOADING. Linking is fine, loading is not.
The rub is that it's fine for a program to start up as a threaded
(libpthread is in the mix of libraries) or a non-threaded app (no
libpthread, and certain symbols get bound to stubs in libc).
What is not ok is for a program to start non-threaded and then try to
become threaded by dlopen()ing libpthread.
