There is a small bug in the sfio-1999 which manifests itself when sendmail
is delivering to file (.forward -> /var/mail/user) and user quota
is exceeded. The problem is in sfio/src/lib/sfio/sfputr.c (puts), it doesn't
check for an error from _sfflsbuf() (in macro SFWPEEK()) - if an error occurs, 
it starts endless loop.
