Description

When running Charm/AMPI programs under Valgrind, you see memory leaked from the runtime. For things that are one-time small allocations we don't really care too much about freeing them, but they are annoying to sift through. The mainchare's memory is leaked, CmiTmpAlloc's memory, and our MsgPool's memory are some examples. Valgrind supports error suppression files which list errors to ignore. We should make and distribute a suppression file.

See section 2.5 of the Valgrind manual: https://wiki.crc.nd.edu/w/images/3/30/Valgrind-Index.pdf
