30e439b2c5 Registering exception handler for each thread, rather than the whole task. 
This avoids the need to forward exception messages to the debugger, since we can reasonably insist that we're the first handler in the chain for each thread.

e88bcc5184 Document the intention behind mps_ld_isstale rather than the implementation: it captures the intention of testing whether a particular dependency is stale (even though the implementation in fact tests whether any dependency is stale). add new function mps_ls_isstale_any for expressing the intention of testing whether any dependencey is stale. the two functions have the same implementation at present, but the separation gives us the freedom to return a more precise result from mps_ld_isstale in future.

2cf1861e8d Improvements to clarity of weak hash table implementation: 
* TAG_SIZE was changed to TAG_COUNT in the code, so make the corresponding change in the manual.
* Avoid the "+= 2" hack: use TAG_COUNT(UNTAG_COUNT(...) + 1). Clarity is more important than speed here.
* Use obj_unused for unused hash table entries so that there can be no confusion between NULL meaning "unused" and NULL meaning "splatted by the garbage collector".
* Add references from the example code to the notes.

1ad79c5caa Switched mac os x threading to use thix.c and pthreadext.c. 
Also switched to using platform specific Mutator Context code
so that we can read out the registers for instruction emulation
and stack scanning.
Builds on 64-bit but doesn't work because sem_init is unimplemented on
Mac OS X.
Not finished on 32-bit.
