/*
* The following interface is not yet deprecated,
* but may be deprecated in the next release and
* removed thereafter.
*
* The run loop watcher API was originally intended to perform two
* tasks ...
* 1. provide the most efficient API reasonably possible to integrate
* unix networking code into the runloop.
* 2. provide a standard mechanism to allow people to contribute
* code to add new I/O mechanisms to GNUstep (OpenStep didn't allow this).
* It succeeded in 1, and partially succeeded in 2 (adding support
* for the win32 API).
*
* However, several years on, CPU's are even faster with respect to I/O
* and the performance issue is less significant, and Apple have provided
* the NSStream API which allows yoiu to write stream subclasses and add
* them to the run loop.
*
* We are likely to follow Apple for compatibility, and restructure code
* using NSStream, at which point this API will be redundant.
