- The multi-thread X server and multi-thread Xlib are two different things.
- Stephen Gildea presented a paper at the X Tech. Conference, which is
- published in full in Volume 5 of the X Resource. I'll let Stephen go
- into more detail here, if more is necessary.
-
- In a nutshell however, it has been publicly stated that R6 will have both
- the multi-thread X Server and multi-thread Xlib.
-
- Unfortunately, Xt and the Widgets are not re-entrant, so the mere avail-
- ability of threaded Xlib won't allow applications Xt-based applications
- to use threads...
