Comment:

 Reason that installing signal handlers is bad: if the events happen after
 the DLL has been unloaded it will dispatch into non-loaded code. This is,
 obviously, bad.

 Another solution would be to uninstall them when the DLL is unloaded, but
 not installing them in the first place is probably the right thing.

 cf dup #747
