23.0.60; Occasional hangs in flyspell-mode and ispell-word |

In connection with flyspell-mode and ispell-word, sometimes Emacs
hangs indefinitely and cannot be interrupted with C-g. When running
Emacs inside gdb and doing a backtrace when it hangs, I get:

Here is a more verbose session, single-stepping after Emacs hangs. At
various points, I tried "C-g" in Emacs, and after some tries the input
seems to be detected at last. When Emacs isn't run inside gdb and
begins to hang, I've never managed to unblock it. It simply consumes a
lot of CPU and is completely unresponsive then.
