Where's the source-code for base::Thread

I was looking up something, and stumbled upon this code:

http://google.com/codesearch?q=kBrowserThreadNames

Where can I find the source for 开发者_运维知识库base::Thread?

(Thing is, in debugging something running under firefox.exe, I notice Gecko_IOThread is setting it's thread name in some kind of way and wanted to look up how.)

A quick Mozilla MXR lookup seems to indicate that it's defined in mozilla/ipc/chromium/src/base/thread.h

Edit:

I was also curious about the presence of Chronium code in Mozilla so I googled a bit and found this on the blog of Benjamin Smedberg the commiter of the code:

IPDL is a language which precisely describes the messages that can be passed between processes, and allows developers to define a state machine and error handling conditions for messages and resources shared across processes. IPDL layers on top of an IPC stack that Mozilla copied from the Chromium codebase

Just click your way into the code...
