bug#2695: 23.0.91; ffap ping hung Emacs on OSX

[David Abrahams]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I did `C-x C-f' while point was on boost.lists.boost.org and emacs
became permanently unresponsive.  It didn't appear to have any child
processes I could kill, although I that was only after I had done a
`C-g'.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Applications/Emacs.app/Contents/Resources/etc/DEBUG for instructions.
