Class Pike.Watchdog

Description

A Watchdog that ensures that the process is not hung for an extended period of time. The definition of 'hung' is: Has not used the default backend.

An important and useful side-effect of this class is that the process will start to respond to kill -QUIT by printing a lot of debug information to stderr, including memory usage, and if pike is compiled with profiling, the CPU used since the last time kill -QUIT was called.
