Miguel,
FWIW, if memory is released in hb_vmQuit() and assuming you build
with memory statitics (as it's clear you do), than there could be no
memory leak, because all hb_vmQuit() does is use normal GC!!!
IOW, the memory blocks must be held by RDD, and then probably
released in hb_rddShutDown(). So you probably need to review
dbCloseAll() compared to hb_rddShutDown() to find the difference.
