Suppress glib/gthread leaks in component build.

tools/valgrind/memcheck/suppressions.txt

 # There are four kinds of suppressions in this file.
 # 1. third party stuff we have no control over
 #
 # 2. intentional unit test errors, or stuff that is somehow a false positive
 # in our own code, or stuff that is so trivial it's not worth fixing
 #
 # 3. Suppressions for real chromium bugs that are not yet fixed.
 # These should all be in chromium's bug tracking system (but a few aren't yet).
 # Periodically we should sweep this file and the bug tracker clean by
 # running overnight and removing outdated bugs/suppressions.

+   glib/gthread malloc leak in component build

These kinds of leaks from system components that we don't control should go at
the end of section 1.  Search for "# 2." and put it before that.

Done.

This file uses 3 space indents.  Yes, I know it's weird.  I don't know who
started it.

[Ryan Hamilton, 2013/04/18 18:16:53]

Woah!  How did those tabs get in there.  Sorry!  (Since this a .txt file, I'll
bet my emacs indenting config is confused).  Done.

Are you reasonably sure this happens once per thread creation?

[Ryan Hamilton, 2013/04/18 18:16:53]

I have no idea whatsoever :(  All I know is that these errors show up ever time
I run net_unittests under valgrind when build via the component build, but do
not happen in the regular build.  Since they appear to originate in
glib/gthread, I think they're not "us", but I really don't know anything beyond
that...
