I should have read the docs for std.signals first, it states: "Not safe 
for multiple threads operating on the same signals or slots." The thing 
is, notifyRegister itself is threadsafe, but when the delegate that it 
stores is called all threads are halted so it's really not safe to use 
at all in a multithreaded program if you aren't very careful.
