I've fixed the leak in the process module; thanks for the report.

There are still 32 bytes leaked by Zorba itself for the dlopen() handle.
I *believe* this is intentional, and that we do not "correctly" close
dlopen()'d libs on purpose to support libjvm-based modules - the JVM
does not respond at all well if it is started more than once in a single
process. Those 32 bytes should be leaked once per module used in the
Zorba process, so it does not amount to much (there are only a few dozen
modules that could possibly be opened, so the max leakage is less than
2k).
