the inferior in the test deliberately does not lock a mutex when accessing the watched variable.
The reason for that is unclear as, based on the logs, the original intention of the test was to
check whether watchpoints get propagated to newly created threads, which should work fine even
with a mutex. Furthermore, in the unlikely event (which I have still observed happening from time
to time) that two threads do manage the execute the "critical section" simultaneously, the test
will fail, as it is expecting the watchpoint "hit count" to be 1, but in this case it will be 2.
Given this, I have simply chose to lock the mutex always, so that we have more predictible
behavior. Watchpoints being hit simultaneously is still (and correctly!) tested by
