New issue 17441 by [email protected]: tools/valgrind/chrome_test.py has bad  
timeout behavior when running dsymutil on mac
http://code.google.com/p/chromium/issues/detail?id=17441

A developer reports:
"valgrind_test.py runs dsymutil until completion (which
takes 4h on my machine – I only have 2GB ram), but
if dsymutil takes longer than 1800 seconds, the script then dies.
It would be preferrable if dsymutil would be killed after 1800 seconds,
or if there was no timeout. Letting dsymutil
run until completion and then failing if it took longer than the
timeout seems pointless.
I will simply increase the timeout to make this work on my machine, so
this is not urgent for me, just wanted to point it out."

This is because tools/purify/common.py's RunSubprocess uses
a blocking read, and can only check timeout between lines.
It should switch to an asynchronous timeout.
