I'm entertained that this hack is now an official tested module. :)

webkitpy/common/thread may be a more appropriate location for this.

Rename id to thread_id, so that it's more obvious what kind of ID this refers to?

Also, nothing about this method seems specific to wedged threads, log_thread_stack might be a better name.

Can this be called _find_thread_stack, to indicate that it's an internal-only method.

> Tools/Scripts/webkitpy/common/system/stack_utils.py:62
> +def log_stack(logger, stack):

Assuming you don't need this in your other patches, can this be called _log_stack?

> +    """Log a stack trace to log.error()."""

Doesn't actually log to log.error anymore.

it looks like common/thread has stuff that uses threads. It might be a better place for the message_broker classes if we moved them out of layout_tests. I think this stuff is more appropriately located with other system-specific code.

Sure.

Well, it does log the string "wedged" :). I'll pull that out as well.
