It's possible to drop from DPC to userlevel (in effect, replacing the currently executed code). In fact, signals are trivial to implement using DPC.

>Of course, since Unix signals are used for so many very different purposes, they cannot and should not be replaced by a single new mechanism.

Unix signals are MISused for many purposes. They are broken and should be deprecated.
