Yes! This is exactly the kind of ugliness we get into by trying to reinvent the
wheel, IMHO. Unless we are able to provide every feature that is currently
available in the BSD socket interface, someone will be unhappy. And slapping an
MPI wrapper around every possible variation will be extremely messy.
Since a tidal wave of support has yet to appear for the SAPHIR_JOIN idea, I'd
like to propose the following alternative: How about if we only define
blocking, collective versions of ACCEPT and CONNECT to handle the simple/common
cases, but then also add SAPHIR_JOIN to provide all of the fancier
functionality for those who need it? Seems like a solid, middle-ground
