   Nevertheless, according to my debug,
I expect that most targets using 
i386 hardware watchpoints and 
not calling i386_cleanup_dregs
will show this problem.

   I think that this is a really nasty bug for 
the i386 linux target for 5.1 release....

    What do we do about this?
I proposed to add a call to i386_cleanup_dregs
for all targets using the standard 
i386 hardware watchpoints, but 
Eli seems still not convinced by my reports....
