BacktickTest#test_backtick_huge hangs on OSX #53

Closed dblock closed 9 years ago

dblock commented 10 years ago

The yes | head -50000 hangs on OSX. The process is still there, either the piping doesn't work or something else? Running the command in bash obviously is fine. Either way posix-spawn ends up waiting on io.read.

Not able to repro a test hang here:
