2401957e62 Extend forktest so that it does allocation before the fork and collection afterwards; this ensures that we hit the read barrier and thus exercise the exception handling. 
After forking in the child, re-create exception port and exception thread, and re-register the (only) thread with that port.

bb8869368c Storing the pointer to the stack frame where setjmp was invoked, rather than the address of the jump buffer, as the hot end of the mutator state, because callee-save registered might be stored on either side of the jump buffer by the compiler. 
Removing the unnecessary assumption that the stack ends are word-aligned.

Consistently use the type "Word *" for pointers into the stack or into saved registers.
