Turns out USR1 is reserved by the JVM on pretty much every platform but Mac, so only expose USR2 for

injected handling by subclasses.

I had a nice version of this that allowed user controlled handling for any signal to be injected.
Unfortunately it used multibindings from guice, and I'm loathe to add a dependency to narya just for
that.
