Hello Robert,

Can you elaborate on that?  CHICKEN marks all file descriptors it opens
as nonblocking, and most eggs attempt to do so too, if possible.  The
core system comes with a thread scheduler which automatically puts
threads to sleep when they're reading from or writing to an fd that
isn't ready.  So, the system is supposed to do automatically what you're
exposing here manually.  If it doesn't, that would be considered a bug.
