I haven't yet had time to go through your test cases, but I did just
find and fix a garbage collection bug in the HDF5 module that could explain
the problem. The new version is:
ftp://ftp.swarm.org/pub/swarm/src/testing/hdf5_1.2.tar.gz
Btw, I don't see a big explosion in memory loading my datasets, but
these aren't `compound' HDF5 types that map into data frames...
