It seems reasonable to me.  I looked through the patch and didn't see
anything I disagreed with.

I'm curious why these new scripts are attached to the program space and
not just the objfile from which the section came.  But, I don't think it
really matters.

I'm somewhat concerned about security.  I don't know why I didn't think
of this before :-(.  The issue is that either approach can result in
random Python code being loaded into gdb.

One idea for a fix would be to check the script file's ownership and
permissions before reading it.  I think we'd need to allow files to be
owned by the current user or by root in order for this to work nicely in
the distro case.
