Hi Calvin, Thank you for this report. I wonder if you might have better luck if you set $PREFER_ALTERNATE_ALARM = 1; in lib/Forks/Super/SysInfo.pm. If that helps, I could make that the default setting in MacOS. Best, Marty O'Brien

In the test report, t/40j-timeout.t passes but t/40a-timeout.t, t/40d-timeout.t, and t/40g-timeout.t all fail. This indicates that your system would benefit from using the "poor man's alarm", so I will enable it for all darwin users in v0.88. -- Marty

Oh wow! You responded! Sorry, given my previous record on reporting bugs to RT, I was expecting (at best) to hear something a few years from now. So, changing `if ($^O =~ /bsd/) {` to `if ($^O =~ /bsd|darwin/) {` in .../system-limits.PL and doing `make && make test` did the trick. B-) Thus, if it helps, I can confirm setting `$info{prefer_alt_alarm}`/`$PREFER_ALTERNATE_ALARM` to 1 on darwin fixes the timeout test failures I originally reported. Below is the resulting output for the .../t/40*-timeout.t tests: t/40a-timeout.t ............... ok t/40b-timeout.t ............... ok t/40c-timeout.t ............... Forks::Super::Job::_config_timeout_child(): quick timeout at /Users/cal/build/Forks-Super-0.87/blib/lib/Forks/Super/Job.pm line 1947. t/40c-timeout.t ............... ok t/40d-timeout.t ............... ok t/40e-timeout.t ............... ok t/40f-timeout.t ...............

Enabled poor man's alarm by default for MacOS/darwin in 0.88. But there are still no CPAN tester reports from darwin systems, so I don't know what to think.
