im following stable, hence it's till calling itself 9.2-PRERELEASE, but
I did a sync this morning - local time, after rc3 was anounced.
but after 3.45 minutes is hung, data in 
	ftp://ftp.cs.huji.ac.il/users/danny/freebsd/core.txt/1

I can't easely revert r250907, since i'm using mercuriall, but if someone
can send me the pre r250907 files, i'll try.

thanks,
	danny
