As in when emitting the signal too frequently from multiple threads?

For my personal education, what happens behind the scenes when a signal is sent 
from one thread to a slot in a different thread? Can I assume there's some kind 
of fifo that ensures signals are delivered in order of being sent and such that 
producer and consumer don't try to modify (access) the queue concurrently?
