The application runs fine, even after I tell it to shut down, it keeps 
going and going and going .... :-)
Obviously SIGKILL takes care of it, but shutting db engines with SIGKILL 
might lower confidence in production systems.

When I upgrade, how do I best approach the problem, if itīs mysql or 
something in the library associated with delivering signals? I have not 
patched mysql to use process scope threads so I suppose everything runs 
system scope. Our in-house applications which also use threads, some 
quite heavily, get SIGTERM just fine so my suspicion would be something 
in mysql disagrees with the threads implementation in FreeBSD.
