Bug 153483 – kill-old-processes: allow to specify on the environment of the bot a list of process that should be killed.

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

We are having an issue with the GTK+ bots because of bug 127352 that is causing that thousands of at-spi-bus-launcher and dbus-daemon process remain open.

On r166798 I tried to workaround this by killing dbus-daemon on the script kill-old-processes that the bots run before any new build.
However this turned out to be problematic for the performance bots so it was reverted on r169343.

So, I think we still want to kill dbus-daemon (and maybe at-spi-bus-launcher) also on the test bots but not on the performance bots.

An idea to achieve this is to implement on kill-old-processes support for killing any task defined on a given environment variable.
This way the admin of each bot can set this variable accordingly

LGTM, let's add this environment variable to be able hack bots easier.

> Tools/BuildSlaveSupport/kill-old-processes:111
> +    tasksToKill = os.getenv('WEBKITBOT_TASKSTOKILL', "").split()

nit: Could you use '' or "" for both parameters to have better looking code?
