squid-3.0.STABLE26: bug 3113: Squid can eat far too much memory when uploading files

Hi,

Some questions about bug 3113 and squid-3.0.STABLE26

http://bugs.squid-cache.org/show_bug.cgi?id=3113
"Squid can eat far too much memory when uploading files."

a) Does anyone have a backport for this bug to squid-3.0?
The fix is commited on squid-3.1 and squid-3.2 but a patch does not
appear to be avaiable
for squid-3.0.

b) Assuming the answer to question 'a)' is no:
Is anyone able/willing to review the attached patch?
This is a backport (or at least an attmept) to squid-3.0.

The 'patch' is based on:
* http://bugs.squid-cache.org/attachment.cgi?id=2327 - "Possible fix,
fourth iteration"
* http://bazaar.launchpad.net/~squid/squid/3.1/revision/10171 - "Bug
3113: Squid can eat far too much memory when uploading files"

[I obviously tested this and everything appears to be working but a
review would be appreciated]

Best regards,

Bram
