+Subject: [PATCH] partial memleak fix
+
+This patch was created by JP (twitter: @canoeberry) based on a memleak fix by Dirk (emacs committer) below:
+https://github.com/mirrors/emacs/commit/57ae6509a3b6a274f89b9caea0284c6156470625
+
+This memory leak is fixed in the trunk as of now and will be in the next official release: 24.4.
+
+However, many of us using cocoa emacs on Mavericks experience random spikes in cpu and excessive resource consumption due to distnoted. This patch potentially fixes emacs-related distnoted issues you may be experiencing.
+
+Steps to use this patch:
+
+You can download a patched version of the source code below:

+Alternatively, you can patch it yourself:

+2. download emacs
+3. apply patch
+4. do the configure, make stuff
+5. enjoy
+
+curl -O http://ftp.gnu.org/pub/gnu/emacs/emacs-24.3.tar.gz
