Tcl Source Code

	* tests/zlib.test: Use nonblocking writes in single-threaded IO
	tests to avoid deadlocks when going beyond OS buffers [Bug 3428756].
	Tidy up [chan configure] flags across zlib.test.

	* unix/tclUnixCompat.c (TclpGetPwNam, TclpGetPwUid, TclpGetGrNam)
	(TclpGetGrGid): Use the elaborate memory management scheme outlined on
	http://www.opengroup.org/austin/docs/austin_328.txt to handle Tcl's
	use of standard reentrant versions of the passwd/group access
