It'll be returned to you shortly as a duplicate of a bug that
encapsulates a larger set of outrun-the-collector issues.
A number of these issues have been mitigated in SnowLeopard, but it is
still possible to outrun the collector (and quite easy with
pathological test cases, as you indicated).
In general (and for the benefit of the rest of the list), GC is
optimized for best performance within a running application. There
are any number of pathological patterns -- micro-benchmarks, if you
will -- that can demonstrate serious performance issues. If you
write one, please file a bug with it -- while the goal is real world
performance, the team still does appreciate collecting edge cases and
making them work better, too.
