function in case of a database deadlock.
This is a function intended to be used to wrap database calls such
that they perform retrys with exponentially backing off sleeps in
between when a DBLockDeadlockError exception is raised.
A 'max_retries' parameter may optionally be passed to prevent it
from retrying forever (in which case the exception will be reraised).
d = DB(...)
d.open(...)
DeadlockWrap(d.put, "foo", data="bar") # set key "foo" to "bar"
