W.C.A. Wijngaards 55e9532d16 - Fix after malloc failure for stats, then it drains the pipe 
so the internal messaging stays correct. Also it does
  not exit the server if stats pipe communication fails.

W.C.A. Wijngaards 5ae979bb6e - Fix that on malloc failure during accept of TCP, the 
socket is not left to cause a read event loop. It uses
  slow-accept to delay accepting new connections, if
  that fails it drops the new connections. When the tcp
  connection usage is full, it waits for 50msec, to allow
  existing queries to be resolved. Thanks to Qifan Zhang,
  Palo Alto Networks, for the report.
