<p>Ah, I got it! Right after restarting the VM (I stepped over #snapshotAndQuit in a debugger), OSProcess in mingw suddenly stopped working (i.e., timeouts only). After evaluating OSProcessAccesssor initialize again, it works again! I have no idea why ...</p>
<p><br>
</p>
<p>Maybe we want to make this default behavior, at least for Windows, by registering this in a #startUp: method? But I don't have a good overview of OSProcess, maybe there is some other state which must not be reset.</p>

<div class="PlainText">Hi Christoph,<br>
<br>
OSProcess for Windows is incomplete and most of the OSProcess/CommandShell<br>
functionality that you see on unix (Linux, OS X) is not going to<br>
work.<br>
<br>
Levente's ProcessWrapper package may be more suitable:<br>

<br>
I'm assuming you are running a Windows VM. If you are using a VM<br>
for Linux, I don't know what will happen, but Windows does not<br>
support the unix fork() semantics so I expect that there would<br>
be limitations.<br>
