:after this ttyv is complete locked, ^C, ^Z etc. don't work.
All right, from various bug reports I have reproduced the
cache-lock issue and I am working on a fix. It could take a while,
I am also fixing some lookup synchronization issues that cause buildworld
to fail.
Basically the deadlock is due to the new API trying to resolve a
namecache node, holding a locked namecache record and trying to lookup
the vnode, while at the same time the old API is holding a locked vnode
and is trying to enter the file with cache_enter(). They trip over
each other and, poof, deadlock.
There are also namespace issues with, e.g. buildworld. If you get weird
failures, like files that the system thinks don't exist but which plainly
do exist, or vise-vesa, I have also reproduced that one and I am fixing
it at the same time.
