Fix signal handler

[elfring]

The function “exit” does not belong to the list of async-signal-safe functions. I guess that a different program design will be needed for your function “printstats”.

[marckleinebudde]

What do you suggest? Use _exit() instead?

[elfring]

Use _exit() instead?

This could be one possibility.

Would you like to consider other software design options?

• sigwaitinfo()
• Self-pipe trick
• Signal-safe locks

[elfring]

I would prefer to clarify acceptable software design directions before contributing patches in a source code format.

I'm not familiar with your proposed alternatives, please illustrate them in form of patches, etc...

[elfring]

The proposed alternatives are already illustrated by other information sources. Would you like to become more familiar with the choices?
