[patch] Fix for bz14333 -- race between atexit() and exit()

[Joseph Myers]

I note the commit message just said "Fix BZ 14333".  Can people please 
include the more detailed descriptions of changes made, as in their 
mailing list postings, in the commit message?  There are certainly some 
simple changes for which just a summary line is sufficient explanation, 
but I don't think this was such a change.  Descriptive commit messages are 
especially important if we stop using ChangeLog entries in future.

(This does mean it's good practice, when making a series of revisions of a 
patch, for each successive revision to have both the full self-contained 
explanation, updated for that patch revision, such as would go in the 
commit message, and a description of what changed from the previous patch 
version, which won't go in the commit message.)
