PatchSet 4037 
Date: 2007/02/14 02:30:55
Author: rousskov
Branch: squid3-icap
Tag: snapshot_b4BodyPipe 
Log:
- Support printing refcounted pointers to ostreams. When printing,
  report the reference count after the raw pointer. This makes debugs()
  statements simpler and their output more informative. Null pointers
  are printed as a "NULL" string.
