Links doesn't use threads. It's based completely on select(). It forks (on
Unix) or spawns thread (on OS/2) only when it needs to do lookup (can be
avoided with option -async-lookup 0) or when it spawned some user viewer
and needs to wait() for it. fork/thread routines are very simple, they
don't touch any global variables and thus the same routine can be run from
a fork()ed child or a thread.
