This results in probe_access returning NULL but the x86 access_ptr function happily accepts an empty haddr resulting in segfault hilarity. Check for an empty haddr to prevent the segfault and enable plugins to track all the memory operations for the x86 save/restore helpers. As we also want to run the slow path when instrumenting *-user we should also not have the short cutting test_ptr macro.

This can be useful if the problem being debugged triggers a reset or shutdown. This can be tested by making a recording of a machine that shuts down, then using -action shutdown=pause when replaying it. Continuing to the end of the trace then reverse-stepping in gdb crashes due to invalid runstate transition. Just permitting the transition seems to be all that's necessary for reverse-debugging to work well in such a state.

That commit causes reverse_debugging.py test failures, and does not seem to solve the root cause of the problem x86-64 still hangs in record/replay tests. The problem with short-cutting the iowait that was taken during record phase is that related events will not get consumed at the same points (e.g., reading the clock). A hang with zero icount always seems to be a symptom of an earlier problem that has caused the recording to become out of synch with the execution and consumption of events by replay.

This can be seen when replaying a trace that has characters typed into the console, an examination of the log shows they are not recorded.

In this case, (a) holds the plugin lock, and starts an exclusive section, waiting for (b). But at the same time, (b) is waiting for plugin lock. The solution is to drop the lock before entering the exclusive section. This bug can be easily reproduced by creating a callback for any tb exec, that allocates a new scoreboard. In this case, as soon as we reach more than 16 vcpus, the deadlock occurs.
