This cuts Var_Parse in half! and allows the modifier logic to

Add new unit-test, to check that certain error cases are handled
correctly.

At the same time we need to add a ReadAllMakefiles() for the case

functions work. When they allocate storage that needs to be freed, instead
of setting a boolean, set the pointer to be freed. Plug some more memory

Looks like it was intended as a minor (and pointless) optimisation to
remove a free() malloc() pair.

It isn't clear that it ever worked, if it did it has almost certainly

I suspect it was written to attempt to use a 'farm' of diskless sun3s.
In any case the apparant random assignment fo jobs to other systems doesn't
actually seem like a good idea!
Things like 'distcc' han be used to help slow systems run native builds.
Removing this code also simplifies make, and should let me speed up some of
its processing - without worrying about bitrotting it further.
push a byte through the (now badly named) exit_pipe and call JobRestartJobs()

Part of a plan to remove JobSigLock() and the zillions of system calls

De-optimise the getting of a job token so we don't re-order the job

This might have helped etc/Makefile, but isn't enough.

You can now put .NOTPARALLEL in a submake of a recursive make (where it is

You can also specify .NOTPARRALEL in the root makefile of a large recursive
make and have the submakes run multiple commands.
Add some diagnostics printfs (enabled with -dp) to the parser.

of errors in other branches of the make (ie those running in a different
make process). The cost of reading and writing a byte from the pipe

Defer replacing job tokens until we've decided there is an error.
If we detect an error in another branch of the make, then call Fatal(),

Now parallel makes actually stop with the failing command on the screen.

If we are aborting, remove all the 'normal' job tokens and add an 'error' one.
If we get an 'error' token, remove any other tokens, re-insert the error

Add the current pid to some of the DEBUG(JOB) traces.
Combined effect is that parallel makes actually stop some fairly shortly

After all with -s you wouldn't know the command for a non-parallel make.
