* Fix uds listener hanging on accept
UDS listener was hanging because the accept method would return
`Poll::Pending` without registering the task to be awoken in the case
when underlying unix listener returns a WouldBlock that gets converted
to None. This is a hacky fix for this case.
Should fix#248
* Test simulating uds ping-pong server/client
This one should reproduce #248 bug to prevent further regressions.
* Code review fixes
Previously all of the into_raw_fd implementations only returns a copy of
the inner RawFd, while still holding the ownership of the file
descriptor when returning for into_raw_fd. Since `self` is dropped at
the end of into_raw_fd, the returned file descriptor will actually be
closed, render the function unuseable.
The patch makes sure that into_raw_fd actually takes the ownership of
the file descriptor all the way from the inner IoHandle. To achieve
this, I have to use an Option in IoHandle to store the I/O source. It's
not pretty, but I cannot come up with a better way.
