Yep, I figured it out later. While the other threads were idle, one
was doing garbage collection - the offending thread above.

I'm surprised that GC is not distributed among the available CPUs,
though - maybe my understanding of GC is faulty. I did read this:

"If not managed, garbage collection is one of the biggest bottlenecks
for an application, especially when running on symmetric
multiprocessing (SMP) server machines."
