fhandler_fifo::take_ownership() is called from select.cc::peek_fifo and fhandler_fifo::raw_read and could potentially block indefinitely if something goes wrong. This is always undesirable in peek_fifo, and it is undesirable in a nonblocking read. Fix this by adding a timeout parameter to take_ownership. Arbitrarily use a 1 ms timeout in peek_fifo and a 10 ms timeout in raw_read. These numbers may have to be tweaked based on experience. Replace the call to cygwait in take_ownership by a call to WFSO. There's no need to allow interruption now that we have a timeout. |
