Description:
This contains Chromium's locally patched copy of tcmalloc.
Contents:
chromium/
The chromium patched sources, copied from the vendor/
subdirectory and containing our local modifications.
We only copy over the vendor/src/ subdirectory (the only piece
we need) but still leave it in a chromium/src/ subdirectory to
keep the directory structures in parallel.
vendor/
Vanilla sources from upstream:

Last Changed Rev: 144
Last Changed Date: 2012-02-04 00:10:11 +0000 (Sat, 04 Feb 2012)
HOWTOs:
Take a new version from upstream:
1) Grab the revision:
$ svn export [-r {tcmalloc-rev}] \
http://gperftools.googlecode.com/svn/trunk \
vendor-{tcmalloc-rev}
2) Check for added or deleted files:
$ diff -q -r -x .svn vendor vendor-{tcmalloc-rev}
3) Copy the new revision on top of the checked-in vendor branch:
$ cp -r vendor-{tcmalloc-rev}/* vendor
C:\> xcopy /e/y/i vendor-{tcmalloc-rev}\* vendor
4) Make all vendor files non-executable.
$ find . -executable -type f -exec chmod a-x {} \;
5) "svn add" or "svn rm" added or removed files (based on your
"diff -q -r" output from above)
6) Create the CL, upload, check it in:
$ gcl change CL
$ gcl upload CL
$ gcl commit CL
Note the revision number since you're going to want to merge
that to the local chromium branch.
Merge a new upstream version with our local patched copy:
1) Merge the local revision to chromium/src
$ svn merge -c {chrome-rev} svn://chrome-svn/chrome/trunk/src/third_party/tcmalloc/vendor/src chromium/src
2) Resolve any conflicts
3) Create the CL, upload, check in:
$ gcl change CL
$ gcl upload CL
$ gcl commit CL

- Converted to utf-8 with: vim +"argdo write ++enc=utf-8" *.h *.c
