Unfortunately, the numbers are retrieved in a loop.  To be extra ex-
plicit, file descriptors from accept(), pipe() and friends.  I can't
see any way that does not involve either 1) memory allocation/freeing
or 2) synchronization.  Both seem unnecessary code bloat for such a
simple task.

I did not see it at the first glance at the FAQ.
