950c53fc2b Fix thread starvation for request in http backend by using a FIFO for thread waiting for a connection to be freed 
Replace the sleep by a wait on an event triggered by the thread freeing the connection
Improve the test to output stats seen below and use the proper amount of threads on low core systems
