Message 81155 - Python tracker

FWIW, I put an alternative in the sandbox /dbm_sqlite/alt/dbdict.py and
am attaching a copy here.  The idea is to emulate gdbm's fast mode and
delay all writes until closing.  That lets us subclass from dict and get
high-speed lookups, sets, and deletions.  Freeing ourselves from an DB
also gets us a choice of ultra-portable file formats (json, csv, pickle,
eval).
