After the first OOPS most programs that try to write something
to the fs's will OOPS... and I up'd my puter from .64 to .72 because it had
(less serious) OOPSes... after a few OOPSes all the progs which try to
read will "hang" ... the odd thing is that sysklogd got some of the
OOPSes saved ;)
will send the other OOPSes in another message when I get them ksymoopsified ;)
