I was looking at Host.requestCreateAttachedProc.
I don't see a way to set the environment or working directory
of the child process.
Perhaps something like ProcessBuilder (new in 1.5) could be used
as a model.
Yes, and in addition and in particular, a mechanism for also extracting that
same information from an existing running (or core) process.
A << re-run this process >> menu item will require that.
