Comment (by Chris Johns):

 LibBSD `select()` call is https://git.rtems.org/rtems-
 libbsd/tree/freebsd/sys/kern/sys_generic.c?h=6-freebsd-12#n998 and it
 says:
 {{{
 /*
  * The magic 2048 here is chosen to be just enough for FD_SETSIZE
  * infds with the new FD_SETSIZE of 1024, and more than enough for
  * FD_SETSIZE infds, outfds and exceptfds with the old FD_SETSIZE
  * of 256.
  */
 }}}
