/** This class implements a nonblocking writer. /** Simple wrapper providing periodic flushing to a disk-backed file.
* Most people writing an ircd give little thought to their disk
* i/o. On a congested system, disk writes can block for long
* periods of time (e.g. if the system is busy and/or swapping
* a lot). If we just use a blocking fprintf() call, this could
* block for undesirable amounts of time (half of a second through
* to whole seconds). We DO NOT want this, so we make our logfile
* nonblocking and hook it into the SocketEngine.
* NB: If the operating system does not support nonblocking file
* I/O (linux seems to, as does freebsd) this will default to
* blocking behaviour.
