Subject: [PATCH] tests: Skip expensive speedup test/benchmark by default.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With this change, ‘make check’ runs in 230s on x86_64-linux-gnu (4-core
CPU) instead of 880s.

* tests/speedup.scm <top level>: Exit with 77 when
‘FIBERS_EXPENSIVE_TESTS’ is unset.
