No. So far, there was only one bug report on SF (that I know of)
where GC was not triggered early enough.

In that case, the problem was that there were large strings attached
to the cyclic garbage that consumed lots of memory, but contributed
little to the object count.

So any application that knows it creates cyclic garbage "on purpose"
should explicitly invoke gc.collect from time to time to be safe. Most
applications don't need to worry, as they can safely assume that users
have enough spare memory for the garbage.
