Even just releasing JIT memory is still, probably not much, helpful.

The memory pressure handler in WebCore is good, but it could be too late in some cases when webkit thread is very busy in executing JS.

We could check the system memory status before allocating a new JS block, and perform a GC if necessary.

Adding a callback is also a solution, better than nothing, from my point of view.
