Well, it seems that switching compression algorithms could be a
nightmare (or can I do this with ptrepack?).  However, I may have a
workaround: I now open the HDF5 file with tables.openFile at the start
of each process rather than inherit the file descriptor from the
parent.  That works, since it's just concurrent file I/O on the same
read-only file, and the start-up overhead is acceptable in this case.

Happy to try lzo or zlib, though, if you like.

Cheers, Ben
