Each time a roundup tracker instance object is created, it needs to do a
lot of work: establish database connection, load (and process) TAL page
templates, etc.
At present, only the roundup_server frontend caches instance objects to
avoid this overhead. While adding something equivalent to the mod_python
interface (apache.py) is straight forward, I wonder about the implications.
How thread-safe is Roundup ? (In particular, the RDBMS cache handling. ?)
Is it safe to simply turn on caching in apache.py, even in the face of
requests coming in from multiple apache threads in parallel ?

Richard, while I would like to work on this, I'm afraid I lack some
fundamental understanding in order to do this efficietly. Could you
please help me clarify this ?

Thanks,
        Stefan
