I won't be able to attend the JDO meeting tomorrow, because of two 
other, one-time meetings that came up this week.

Michael B.,
you probably also need to attend the EJB3 phone conference, which says 
"urgent" and just got scheduled for tomorrow 8 a.m. (it doesn't say how 
long it will take).

A quick status update on my tasks:

> Double-check locking in the PMF (Martin)

I've been discussing with Marina and Michael B. a couple of code changes 
on the PersistenceManagerFactoryImpl this week.  We're closing in on a 
final solution, which is bigger than we had anticipated originally.

While we started with just a direct fix of the broken synchronization 
code (double-checked locking), we found that the code for the JTA<->PM 
bookkeeping can be significantly improved: by using a thread-local PM 
lookup, we don't need a 'pmCache' table! (so, no synchronization at all)

Michael, Craig, and Marina, find the details in the email thread:
   Re: code review PersistenceManagerFactoryImpl

I'm currently working on a few more code simplifications, which should 
be done very soon.  Marina will help testing in the appserver; and if 
not too much work, Michael B. has offered to test my changes in JDO 
(also need some EJBImplHelper changes backported?).

We definitely need a thorough, final code review with Craig before 
committing any changes.

Still open (no progress since last week).  I hope to get to finish and 
test my JDK5 classfile changes next week.
