No, this is a problem :(

I saw this last night and have been giving it some thought. We might
have to put a separator into the stamp file format to make this easier
to deal with. The downside is that is a TMPDIR layout change :/.

The thing is the bug this solves is serious even if people only rarely
hit it and I can't think of a better solution...

Cheers,
