I will try to get the Tcl thread 2.5 extension for Tcl (and AOLserver) done until end of the year. It will include the threadpool implementation in both Tcl and C, a nice abstraction of threads and nsv_* like interface for shared variables with much larger command set and internal shared-object handling. The channel-passing feature (for Tcl8.4+) with both channel transfer and channel detach/attach functionality between threads is also included. The key feature of threadpool implementation is that is entirely event-loop aware, so application written with event-loop style wont be blocked while waiting on the free pool worker or waiting to collect the result of the posted job. I hope this will simplify much of the code written initialy with event-loop style and being ported to the threads paradigm. The extension will also include an example of a tiny MT-enabled web-server and general purpose command-line server, all done in 100-300 lines of Tcl. Cheers Zoran
