Sylpheed RE agent 3ecb3432f1 docs: the freeze was caught and the stuck-wait probe reports nothing new
The fourth run froze 9 seconds into the watcher's window, in flight, and the
probe built for that moment showed the healthy-run baseline and nothing else: one
pair, the same poller on the same object VA as every healthy run, only the thread
handle differing. No new (thread, object) pair appeared.

So the hypothesis the probe was built to catch is refuted - the freeze is not a
guest thread looping on KeWaitForSingleObject timeouts against ONE object - while
the CPU signature is unchanged from the gdb run: 1255 ticks over 10 s, 401 in the
TimerQueue thread and 292/280 in two guest threads.

What survives is stated as two specific blind spots of the instrument rather than
a shrug: the waits may cycle over DIFFERENT objects, which resets the streak and
makes them invisible to a same-object counter; or they may SUCCEED rather than
time out, which leaves a timeout counter nothing to count and would fit the
kernel-log evidence of a self-suspending worker cycling thousands of times
successfully.

Next is a v2 that counts calls per thread per second regardless of object or
result. The freeze lottery paid out on the first attempt this time.
