[Rick sent me the `lsof` output via email.]

The `lsof` output shows 241 (!) file descriptors used for TCP sockets, all to 
the same host.  That’s /way/ too high.  Each session should have its own 
internal limit to the number of connections it opens to a given host; you can 
pin this using `HTTPMaximumConnectionsPerHost` (which is typically 4) but it’s 
also pinned by the internal workings on NSURLSession.  It seems that this pin 
has come unstuck )-:

How you modify `HTTPMaximumConnectionsPerHost` at all?

Share and Enjoy
