    yum: opt out of SIGKILL as this can lead to RPM database corruption in some situations

    Allow a spawned backend to opt-out of the SIGKILL cancel process, and add a default in PackageKit.conf

    Add a method to disable SIGKILL in PkSpawn

Agree.

Okay. Now with git master, PackageKit only sends a SIGQUIT, and does not
send SIGKILL at all. It's up to yum and rpm to DTRT in this case.
