LWP Quick docs - 2-Sep-90

"lwp.c" is the context switch code.  Should be converted to assembly if this
ever really works.

"intr.aii" is the interrupt handler code.  Also intercepts toolbox and GS/OS
calls.

"main.c" is a sample test program.  Take a close look at it.

"itest.c" is used for debugging the interrupt routines (but essentially
worthless otherwise).

"stuff.m16" is some macros.

"tools.h" holds C defintions for some toolbox routines this uses.

"lwp.public.h" is a public header file for all routines that use LWPs (i.e.,
applications programs).

Link "2/start", "main", "lwp", and "intr" for a demo.  Note this this was
compiled under APW, with APW C and the APW assembler.  No guarantees about
compatibility with Orca/C.

The main problem with this is that any output causes it to crash.  I don't
know if this is a peculiarity of the C library routines or what, but it's
unacceptable since the main idea was to allow a UNIX fork() command for the
//gs.

If somebody can figure out why echoing characters causes a crash, the whole
problem should be solved...  No restrictions on this source code, but if
you can get it to work I want a copy.  No derivatives of this code may be
sold without my written permission (so don't fix it up and turn it into a
huge money-maker without allowing me to get my fingers in the proverbial
pie...)
