Sending messages with attachements is ttoooo sslloowwww

So I repost my message **without** attachement, and with a link to a (not
pretty) personal page just build

http://ourworld.compuserve.com/homepages/cbaribaud

I'm still trying to build a minimalistic multi-threading kernel under
DJGPP....

I have tried LWP (thanks to Florian Schulze for a link to a **working**
version of LWP), but its example 4 hangs under Windows 2000, never at the
same position...

So, I continue my little work ;-)

Eli Zarestkii found a enormous bug in my preceeding release (I haven't yet
read crt0 source code ...) so this release uses standard memory allocation
function malloc for stacks.

I do think that a pre-emptive multi-threading kernel under MS-DOS is a wrong
way, since DJGPP libraries, DPMI and DOS aren't reentrant. The only
efficient solution is to use a natively multi-thread OS, like Linux or
Windows NT.

But, it is still possible to develop a NON pre-emptive multi-threading
kernel (like Windows 3.1)

I will have now to find how to use serial ports without loosing characters,
under MS-DOS AND Windows...

For the moment, I send the current release of my work

Examples 3 and 4 are the same as LWP one's.

Regards

CB
