At least two latent problems should give one pause:
- use of SIGALRM and queue structures in a thread-unsafe manner
- use of numerous async-signal-unsafe functions in onalarm() signal
  handler, and callback functions listed __pmAFregister

To some extent, it's been lucky!

One more thing.  The functions in AF.c are all __-prefixed,
dso-exported, declared only in impl.h, and in this case used by a
client.  I have several times asked what __ prefixing is supposed to
mean, when we use it so arbitrarily.  This is a case in point.
