 sustaining two hits per second max, usually much lower.

 It contains some potential bugfixes.

 to spawn any more (it will block via mutex until a thread finishes).

 In chicken 4.5.7 there is an internal procedure `(##sys#dump-heap-state)'
 which prints statistics to stderr about all objects in the heap.

 It wouldn't hang in such a case, it would generate a "too many open files"
 error.
