No, the disease is fatal.  While painful, the problems being seen when
running the -P1 code are usually not fatal, and ISC is working (with
community help) on getting new code out for the people that are seeing
the problems.

There are many reports of people having problems, but I think that the
percentage of successful installs of -P1 highly outweigh the number of
problems.

Even for people with issues, the vast majority of "problems" that are
being seen with the -P1 code are not show-stopping (higher than normal
CPU and lower query rates).  Those issues are being worked on and the
next "dot release" (9.4.3 and 9.5.1) should address them.

Please, PLEASE, deploy the -P1 code.

ISC fully understands the need for stability and quality code.  We
strive for both, but as you have noted, this issue (and related
operating system dependent issues that we were not aware of) has been
extremely stressful for everyone involved.

I understand your frustration, but without quality bug reports and the
debugging information that the engineers need to track down the
problems, we are unable to narrow down possible causes.  We are working
night and day on addressing the issues.

I don't speak for ISC, but I do work here.
