Hi Sean,

Yes there is an issue tracker for reporting bugs related to the VM.
This is the Mantis bug tracker at <http://bugs.squeak.org>. Use category
"VM" for things related to the VM. There is also a google issue tracker
associated with Cog development, although I don't think it is relevent
to your questions here.

The plugins used by OSProcess and CommandShell (OSProcessPlugin,
AioPlugin, and XDisplayPlugin) are all maintained independently of
the VM proper. Source is on SqueakSource, and these plugins may be
included in any VM build at the discretion of the platform maintainer.
All three are normally included in the standard Unix VM, but may
not be available or fully supported on Unix Cog VMs. A Windows
version of OSPP with limited functionality is available but not
included with standard distributions. On OS X, the OSProcessPlugin
is normally distributed. I think that AioPlugin would also work
on OS X but is not distributed (I don't have a Mac to test it so
I cannot confirm).

One issue that you reported was due to the out of date plugin on
one of the Mac VMs for older machines. Esteban Lorenzano is the platform
maintainer for these VMs. I don't know if Esteban plans any further
builds for the older series of Mac VM's, but I'm sure that if he
does he'll include updated plugins (but Esteban can answer this better
than me). 

I am the author and maintainer of the plugins, as well as of OSProcess
and CommandShell. However I do not have a Mac, and I do not always
keep up with the latest Pharo versions, so if there are issues beyond
just the out of date plugin, I will appreciate any debugging or patches
that you or others may be able to provide.

Thanks,
Dave
