Just a few notes: this implementation is 95% the same as the one I have
for mingw. I'm even tempted to make them actually share the code,
because it would make changes/fixes to one be used in the other.

It doesn't use a static variable when malloc_tsd_malloc
fails, but unconditionally aborts instead. Using a static variable is
due to fail with multithreading anyways. The 'initialized' variable is
not necessary either, as pthread_key's cleanup function won't be called
unless a non-NULL value has been set with pthread_setspecific.
