1. A method of preventing disruptive computer events in a computing system, comprising:

  • executing a process for controlling an external device, the process having a time-noncritical phase and a time-critical phase;

    controlling the process using a process control application executing on a computing device managed by an operating system by intercommunicating signals between the computing device and the external device;

    during the time-noncritical phase, operating the computing device in a plurality of operating modes including a first mode in which system services and applications other than the process control application are allowed access to resources of the computing device under control of the operating system and a second mode;

    making a determination that the process has entered the time-critical phase; and

    responsively to the determination, automatically transitioning the computing device from the first mode to the second mode in which the access by the system services and by other applications to the resources of the computing device is selectively limited in favor of the process control application.
