The signal handler writes the received signal number as a byte value into the notification pipe. If two signals are received in quick succession, one of the writes may fail with EINTR without writing the byte. This commit will check for EINTR and retry the write. If the error is other than EINTR, a warning will be logged. Note, that: - on systems with sigaction libevent uses sigaction with SA_RESTART - on linux writing to pipe is restartable and firstly it will try to write that byte so linux should not be affected in any form [1].
