Sabine,

I did not yet tested OSProcess but with OSSubprocess (in 5.0) I cannot reproduce the issue:

Polling strategy works:

Delay delaySchedulerClass: DelayMillisecondScheduler.
20 timesRepeat: [OSSUnixSubprocess new
command: 'echo';
arguments: {��
' };
redirectStdout;
runAndWaitPollingEvery: (Delay forMilliseconds: 50) retrievingStreams: true onExitDo: [
�� :process :outString :errString |
�� Transcript show: outString;cr .
�� ].
].

Semaphore-based (child watcher) works:

Delay delaySchedulerClass: DelayMillisecondScheduler.
20 timesRepeat: [OSSUnixSubprocess new
command: 'echo';
arguments: { 'Hi There' };
redirectStdout;
runAndWaitOnExitDo: [ ��
�� :process :outString :errString |
�� Transcript show: outString;cr .
�� ].
].

Using shellCommand: (bash) instead of #command: and #arguments: does work too:

Delay delaySchedulerClass: DelayMillisecondScheduler.
20 timesRepeat: [OSSUnixSubprocess new
shellCommand: ('echo "Hi there"');
redirectStdout;
runAndWaitOnExitDo: [ ��
�� :process :outString :errString |
�� Transcript show: outString;cr .
�� ].
].

Hi Mariano,

if you take the download Image from the Pharo website, then load commandShell and then zinc from the catalog browser and then do

Delay delaySchedulerClass: DelayMillisecondScheduler.
and then
20 timesRepeat: [OSProcess ��command: ('echo "Hi there"').]��

Then you will get the lock.

Does this help to find the reason for the problem?

Regards
Sabine
