Public bug reported:
There are some places that a target plugin's method is called in
'with context.session.begin(subtransaction=True)'.
This causes 'lock wait timeout' error potentially.
--- error is like:
OperationalError: (OperationalError) (1205, 'Lock wait timeout exceeded; try
restarting transaction') ...snip
---
For example say ml2 is target plugin. Ml2's mechanism drivers separates
precommit and postcommit
method so that 'lock wait timeout' error does not occur.
But it is meaningless if ml2 is used under metaplugin.
