[Meeh]

Seem to be a one-time happening. The reason it came is that each time we update trac, trac will alert the paid ones of us that we need to pay attention :p

Unless we experience it more, we can just close this. But please reopen if you have this issue anytime in the future. I would then have to rewrite the python script to do it async which apparently now currently is doing it sync.
