New Revision: 5161

Modified:
   branches/2.1/varnish-cache/bin/varnishd/cache_backend.c
Log:
Add explicit log flushing when backend connections close to keep log
chronology. This is to avoid log lines for the same (reused) FD coming 
before the closing connection when load is high.

Trunk r5160 reworked for 2.1 branch.
