Comment:
This seems to be related to #8311, which was fixed in [8620]
{{{
# Because a cache can fail silently (e.g. memcache), we don't know
if
# we are failing to create a new session because of a key
collision or
# because the cache is missing. So we try for a (large) number of
times
# and then raise an exception. That's the risk you shoulder if
using
# cache backing.
for i in xrange(10000):
}}}
Anyway, that magic 10000 sounds like a code smell at least, probably the
value should be adjustable for different server loads?
Flagging as accepted, at least a comment explaining the consecuences of
that 10000 (what makes it different from 1000 or 100000?) should be added
