------- Additional Comments from Anders Carlsson <andersca at mac.com>
This implements the JSC part of a hang-detection implementation that works
pretty much like the one in Mozilla.

Unfortunately, when turned on this causes a performance regression in ibench.
The other approach I tried (using UNIX signals) proved to be complicated and
error-prone and it too gave a performance regression (albeit a smaller one)
