Hi, I'm testing py4web and I'm stuck with record versioning.
If in models.py I define a trivial table with versioning enabled like this:
### Define you table below
#
# db.define_table('thing', Field('name'))
#
## always commit your models to avoid problems later
#
# db.commit()
#
db.define_table('thing', Field('name'))
db.thing._enable_record_versioning()
db.commit()
I get this error:

I tried to follow pydal source to find the cause, the odd thing is that the
creation of "thing" table seems to go well, but its archive definition
apparently clashes with threadsafe variables (or their lack).
What am I missing?
