LWP 1.1

Date: Who knows?

Original code by Sengan Short and Josh Turpen

PDMLWP 01 : version 1.2
May 15th, 1997 (more or less)

Modified lwpasm.S to call back a new function,
      lwp_findnext(), to implement semaphores and
                     waiting threads.
                     Added ex novo lwp_wait_true,lwp_wait_false,
                     lwp_wait_semaphore,lwp_release_semaphore,
                     and related data types (lwp_semaphore,
                     lwp_time). Minor modifications to _lwp_dead_thread.

May 22nd, 1997       Made a few speedups, and added C++ support.

October 1997
PDMLWP 02  : Version 1.1
Added priority support.
BUGS Fixed:
        Stack allocation for lwp_spawn'ed threads.
        Lots of memory leaks. Code checked using Simon Bullen's (Z)FORTIFY.
        Now, there seems to be none.
        Corrected that problem about the hundreds of warnings at compile
        time.
        Suicide now handled correctly by lwp_kill.

New Featues:
        Thread priorities support added, in a slightly different manner from
        LWP 1.2.
        lwp_kill written anew. There was a serious bug in the processing of
        suicide, so I solved it by creating an always dormant thread (lwp_tcp)
        that frees the stack of the lwp_kill'ed thread.
        This way, there has to be no special processing for the suicide.

Note:   For unknown reasons, IRQ0 (ZERO) doesn't look like working under Win95.
        Perhaps it's used by Win95 for the same purpose.
Note:   I changed my E-Mail address, due to UNBELIEVABLE problems with my
        server. It is now "paolodemarino@usa.net".
