the reason I asked about OSProcess in Pharo 5 was that

OSProcess waitForCommand: 'ls'


never returned.


Maybe its another instance of this problem.�� And it happens everytime.

There is a 50ms delay in the #waitForCommand: method


It looks quite similar indeed. And... both, OSProcess and OSSubprocess have a similar child watcher (I based mine in OSProcess one).
Paul could you inspect the child process from the process browser tool, do an inspect, and check the suspended process? Check the wait time to see if it is 50ms or 20ms etc...that way we can see which part is the "hunging".

hope this helps
