Allan, as you say in the 1.0.2b3 release notes, for commands bash is getting run as an interactive sub-shell rather than a non-interactive one.
A data point that I thought you might be interested in:
* In 1.0.2b1 if I run a command that uses the shell I can't see any additional bash shells pop up in process listings
* In 1.0.2.b3 I can see an additional bash show up with something like: /bin/bash -c 'command'
I wonder if that change in observed behavior has something to do with the issue?
Anyway, just hoping that helps. Thanks.
