bug#15946: 24.3; Mac OS X, Mavericks, distnoted process


From: SB
Subject: bug#15946: 24.3; Mac OS X, Mavericks, distnoted process
Date: Mon, 20 Jan 2014 18:53:52 +0900

After reading reports in this thread that it was fixed in the trunk I
went and applied the aforementioned inline patch to the current trunk
and indeed the distnoted issue seems fixed. Whereas with my patch to
the inline patch the problem seemed a little more tolerable and still
required occasionally killing distnoted (and Emacs.app crashed
although less frequently).

If there is a single commit that can make distnoted behave, it may be
in the interest of others using Mavericks to have this incorporated
into an official point release and close this bug (the distnoted bug
for those affected can be quite severe, locking up the entire machine
in my case). Mavericks is inevitable for many mac users and some
people may not be ready to transition to 24.4 for whatever reasons.

The modified inline patch (only relevant if you use Japanese or some
other language for writing text in Emacs and want seamless language
switching while using various keys/commands) for the current trunk:
