Depends ;) Setting O_NONBLOCK on a fd, and then writing to it without it
accepting the data, simply returns (somewhen) with <= 0 bytes written,
which is interpreted by libICE as an error, so iceConn->io_ok is set to
False and all error callbacks are called. The data is forgotten (besides
that what happened to come through), and _IceWrite simply returns.

As long as an iceConn has the ->io_ok flag to false any _IceRead or
_IceWrite simply returns without producing further errors.


Ciao,
Michael.
