[lldb-dev] ninja check-lldb hangs on OSX

[Todd Fiala]

Separately, the check-lldb command uses the 'dosep.py' multicore test
runner --- which runs multiple tests at a time.

I've caught a few times where that test runner hits some unexpected lock-up
conditions on MacOSX.  Ideally we need to track down and fix those.  The
few times I've looked at it with sample graphs, it looks like some of the
connection logic is locking up.  It's been lower priority since nobody on
the cmake/configure build paths on MacOSX have been trying to run tests.
The two options from here would be (1) have somebody track down the
occasional lock-ups on multicore test runs on MacOSX, or (2) consider
having MacOSX check-lldb switch to run tests via dotest.py (sequential test
runs) instead of dosep.py (runs multiple test directories in parallel, one
worker process per core available).
