pt-kill in version 3.0.7 seems not to respect busy-time any longer

Hello,

we noticed that after the update over the official repository today the pt-kill tool seems not to respect the busy-time parameter like before.

For us its slightly uncomfortable, since we only use it for monitoring processes, but not active kill things, but I could estimate, that this bug hits more people even more harder when using the tool to kill really running queries!

You should investigate it with hurry and fix it asap  ...
