Sorry for the "me too" on this, but well Me too ;-)

I am unable to test this on a FAT32 partition as I don't have one on my or
any other system I work with. Perhaps you could provide strace output? Igor
gave some very good pointers ("Re: rcs ci and co hang") on this list a few
days ago, although it's not the same issue, you could use some of the
instructions to gather the strace output and send some/it to the list.

If it does reach an outrageous size, or you're not to sure what it means, I
don't mind if you send it to me off-list and I'll take a gander (compressed
ofcourse ;-)...
