This means that signal handlers in applications making use

One exception to this rule is for signals raised in response
to watchpoint debug exceptions, where the tag information

(3) Special care should be taken when using tagged pointers,
since it is likely that C compilers will not hazard two

virtual addresses differing only in the upper byte.
The architecture prevents the use of a tagged PC, so the upper byte will
be set to a sign-extension of bit 55 on exception return.

As the system progresses forwards, the executed tasks are put into the tree
