> Doing anything substantial in a signal handler is problematic.

Are the following approaches valid software design options for the discussed use
case?

1. "Self-pipe trick" that was described by Daniel J. Bernstein.
   http://cr.yp.to/docs/selfpipe.html

2. Are lock-free algorithms applicable like an implementation is described in
the article "Signal-Safe Locks"?
