StringNG merge?

Hi all,
  Is it maybe time to resuscitate StringNG, with the target of merging
in time for 3.3?
  I have unrotten the code, which now compiles and passes the unit
tests, with Amos' recent changes to RefCountable/Lockable.
The only API objection I remember (SBuf::terminate() being public) was
fixed some time ago - I guess that the code was ready for merging but
held off due to merge window being closed.
 Only recent change is the renaming of SBuf::findAny to find_first_of
for consistency with std::string.
Feature-branch is at lp:~kinkie/squid/stringng

If we agree, any preference on how to proceed?
