Summary0008090: UnixSignals setup should be more graceful
DescriptionOn this configuration, the OpenSim.exe barely gets off the ground, when it tries to instantiate new UnixSignals. The stack trace below is what is returned when I wrapped the new code in a try/catch block.

Regardless of if this is an issue with the Mono configuration or system libraries, we should probably be a little more graceful.
Steps To Reproduce1. Try to start OpenSim.exe

(Underlying issue may be too old of a Mono version, or missing configuration option in Mono.)

This is a quick and dirty fix, since the Unix signals are a nice feature to have but should not totally block starting a region at all.
