Next over-paranoid question: From reading several sources I
only find that sig_atomic_t is atomic wrt a direct
assignment. Not finding that it is atomic wrt
increment/decrement would render it dangerous for signalling
a global state if signals are delivered or not.

The only reliable trick I found is to use the hack-pipe as
the signalling mechanism itself. I think
http://www.xs4all.nl/~evbergen/unix-signals.html describes a
safe mechanism. The high-level signal handler would become a
fd handler on the reading end of the pipe.
