Comment:
The immediate problem is the FIFO code [http://dev.haiku-
os.org/browser/haiku/trunk/src/system/kernel/fs/fifo.cpp?rev=42116#L694
notifying a read event] when there aren't any more writers. It should
notify a `B_SELECT_DISCONNECTED` instead. It looks like the code is in
need of a general review with respect to `B_SELECT_ERROR` and
`B_SELECT_DISCONNECTED` notifications.
