Yes, and I'm just curious why fatal X errors are handled in the same way
as non-fatal (by x_connection_closed). IIUC if X connection is broken
at the socket level, X protocol command may result in undefined behavior.
Manual says that XIfEvent flushes an event queue and waits for an event
matching the predicate; I don't know how the socket connection was broken
exactly, but it was "broken enough" to wait forever.

Shouldn't we try to check errno x_io_error_quitter? Socket-related calls
should set it in case of error.
