  No, it's not common, and it generally takes a Dane swinging something

Your criticism is grossly unfair.  Throughout the very long time he's
been active in this project, PHK's contribution/breakage ratio has
been unsurpassed.

And btw., the recent stdio breakage wasn't all that bad either, and it
completely happened in userland.  I ended up in reinstalling a system
from backup tapes, so the effect is not different to the specfs bug.

Too much snipping; that wasn't critizism. It was pure jealousy. 8-)

He also said obviously I haven't been playing in the right bits of the

And - who knows - it might be that phk's real middle name is Haegar 8-))).

I think my sarcasm may have gotten lost in transit; please re-read the
message with a big blinking Sarcasm Follows post-it note reattached.  I
have great respect for Poul-Henning's work, especially with regards to his
expertise in the device and buffering mechanisms in FreeBSD.  The degree
to which this is the case will becomes more clear in the near future. :-)

It was almost like that dirpref problem I ran into a few weeks ago, I
upgraded from -stable to -current and I had to reinstall because of it, but
this usually doesn't happen.

It happens from time to time.  VM was really unstable for a period a
few years ago (3.0-CURRENT timeframe) when John Dyson was dinking with
it.  This is why you need to be extra-careful when running -current on
systems with data you care about :-)
