On some platforms (OSX I believe) pid_t (PlatformThreadId) is a *signed*
integer, and on others it's a long long unsigned. I'm not sure, but this might
get you into trouble. The last time I touched this code I was tempted to convert
this to std::ostringstream.

I think that if this passes the buildbots you'll be OK.

(I'll switch to jsbell's suggestion.)
The mac_chromium_compile_rel trybot thought it didn't need to recompile with
this patch, I wonder if that's a bug on the trybot?
