I dunno, this seems like a sophomoric, rose-colored view of variable sharing
without regard to caching, or really any generally accepted guarantees about
POSIX threads.

Two threads see `threads_holding_glib_lock` is "0" and both attempt
acquiring the lock (line 43, xgselect.c)
Or, two threads see `threads_holding_glib_lock` as "2" and glib
lock is never released. (line 37, xgselect.c)
