gpgscm: Limit the number of parallel jobs.
* ffi.c (do_wait_processes): Suppress the timeout error. * tests.scm (semaphore): New definition. (test-pool): Only run a bounded number of tests in parallel. (test::started?): New function. (run-tests-parallel): Do not report results, do not start the tests. (run-tests-sequential): Adapt. (run-tests): Parse the number of parallel jobs.
This change limits the number of tests that are run in parallel. This
way we do not overwhelm the operating systems' scheduler. As a
side-effect, we also get more accurate runtime information, and it
will be easy to implement timeouts on top of this.
Use TESTFLAGS to limit the number of jobs:
$ make check-all TESTFLAGS=--parallel=16
