I'm running (a very recent) Emacs 24 [1] (synced to
77688e1b570f1e74dd092efa6f1d98c369c42273 lisp/ChangeLog: Fix typos.)
that hangs every time I open the following file (locally)

http://hg.openjdk.java.net/jdk6/jdk6/hotspot/raw-file/20dbc199874e/src/share/vm/runtime/globals.hpp

and try do an incremental search (regexp or otherwise) for (say) 
'TraceBytecodes'.

On Debian [2] the instance doesn't recover. The problem also 
exists in OSX 10.7, where Emacs is able to recover, while still only 
very slowly though.

Emacs 23 works just fine on the file on both platforms.
