[Pharo-project] OSProcess - is process done?

[Sean P. DeNigris]

Sometimes, OSProcess hangs even though the underlying command has completed.

For example, on Mac 10.7.3:
    p := PipeableOSProcess waitForCommand: 'ps -ax -o pid,command' "never
returns"
  even though "p upToEnd" immediately returns the output if I use #command:
instead of waiting.

How best to handle this?

Thanks.
Sean
