Comment:

 And this is the torsocks fix.  Since C++ is a thing, and torsocks should
 support people doing various silly and not so silly things in their
 constructors, this is probably better than patching libtcmalloc.

 I ended up implementing my own `pthread_once()` analog since I didn't feel
 that changing libtorsocks to always link against a real pthread
 implementation on Linux was all that great.  Changing the code to use
 `pthread_once()` is easy if people happen to disagree with me.
