[issue4273] cycle created by profile.run

I think we still need to prevent collectable cycles in our Python code.
Here's the situation:

We've got a process that creates many Python objects, and it needs to be
responsive, it's not good for it to block on one operation for more than
100-200 ms. The automatic garbage collection is currently taking on the
order of 2 seconds for this process.

If we can guarantee that no collectable or non-collectable cycles are
being created, we can gradually increase the collection threshold, or
turn off the garbage collector entirely, reducing or eliminating the
blocking overhead of garbage collection.
