scsh-process/tests, branch 1.6.2Egg to add Scheme Shell process notation to CHICKEN Scheme.

The and-let* code assumed that if p was false, it would have a
"pending-before" procedure. Unfortunately, this assumption only holds
when the process would've been forked using "fork" from the
scsh-process egg. If one forked with the "core" fork from CHICKEN
itself, both p and pending-before would be false, which would lead to
a "call of non-procedure: #f" error.

Fix issue with redirection in run/port (and, by extension, run/string)2021-09-14T11:54:29ZPeter Bexpeter@more-magic.net2021-09-14T11:54:29Zurn:sha1:eb97f7d4f6a6428b52f6cd24e54d3e4650f631a0
We would initially create a pipe, dup(2) that onto fd 1 in the forked
process and open an output port on the original fd. This resulted in
a pretty nasty bug: if the fd would be redirected (by number) later,
it would not affect the output port because that was set up to point
to the original fd.
Instead, open an output port to the newly set up stdout and close the
direct pipe port.

Thanks to Vasilij Schneidermann for providing an initial patch.

run*/string* does not exist, and run/string* doesn't raise an
exception on nonzero exit status.

Fix ordering of (= x y) redirection EPF2018-01-26T21:25:23ZPeter Bexpeter@more-magic.net2018-01-26T21:25:23Zurn:sha1:a7fd28ee34353eac9502782ceb0ed3961026f284
Thanks to Diego "dieggsy" for pointing out this incongruity with
scsh-process.
Run signal handler in a separate thread2017-11-18T12:58:13ZPeter Bexpeter@more-magic.net2017-11-18T12:58:13Zurn:sha1:1adc1af6d9b52ad33f0b773cfdcd64573a2b7b9e
This seems to be necessary so that condition-variable-broadcast! works
when the signal handler is running in the same thread as the waiting
thread.
Also unmask (if needed) sigchld in the child process thunk2017-11-10T20:08:02ZPeter Bexpeter@more-magic.net2017-11-10T20:08:02Zurn:sha1:4e420e4d032b550fa6e0193a3bbf04f4db76cc8b
This would be otherwise kept in masked mode because the thunk is in
the dynamic extent of the dynamic-wind.
Don't unmask signal if the signal was already masked before forking2017-11-10T20:03:18ZPeter Bexpeter@more-magic.net2017-11-10T20:00:22Zurn:sha1:a29a4e79aa00d697a564cb3bd7f1f78d7e5d7245
