Operating system: Cygwin
PHP version:      Irrelevant
PHP Bug Type:     Documentation problem
Bug description:  Potential for total failure of uniqid() should be documented

Description:
------------
The source code indicates that uniqid() may completely fail on Cygwin and
return false:

#if HAVE_USLEEP && !defined(PHP_WIN32)
	if (!more_entropy) {
#if defined(__CYGWIN__)
		php_error_docref(NULL TSRMLS_CC, E_WARNING, "You must use 'more entropy'
under CYGWIN");
		RETURN_FALSE;
#else
		usleep(1);
#endif
	}
#endif

This needs to be documented so that unsuspecting web apps don't become
insecure when run on this platform, e.g. giving everyone the same default
password.
