Charm++ parallel programming system

Brian,

Fortunately, both of these are issues on our radar. I believe some of
us here are testing possible fixes to these issues. These should make
it into the next release. We'll let you know once fixes are available
on the main branch of charm's git repository.

Phil, Ralf,
Do chime in if these are already on the master branch.
