Did some backtracing in a debugger; I get an almost identical backtrace from the 
event loop (and not the signal handler) when I call my slot
- through a QSocketNotifier (after writing to a pipe)
- through a QueuedConnection connection invoked from an emit in the signal 

The latter solution also makes it more straightforward to pass the signal number 
to the actual handler.

Is this safe? If it is, wouldn't it be a nice little addition to
