There are two ways nohup(1) might be implemented:
it might mask away the signal, or it might set the handler
to SIG_IGN, both of which are inherited across fork+exec.
So two fixes:

* Make sure to preserve the inherited signal mask at
minit instead of clearing it.

* If the SIGHUP handler is SIG_IGN, leave it that way.

Fixes #4491.

Subject Alternative Names in X.509 certificates may include IP
addresses. This change adds support for marshaling, unmarshaling and
verifying this form of SAN.

It also causes IP addresses to only be checked against IP SANs,
rather than against hostnames as was previously the case. This
reflects RFC 6125.

Fixes #4658.

This is part one of two changes intended to make it easier to debug builder failures.

runOutput allows us to control the io.Writer passed to a subcommand. The intention is to add additional debugging information before and after the build which will then be capture and sent to the dashboard.

In this proposal, the only additional information is the build status. See http://build.golang.org/log/e7b5bf435b4de1913fc61781b3295fb3f03aeb6e

Eyeballing a sampling of the raw number of comparisons shows a drop

there are no situations where this makes *more* comparisons.
