The problem with Runtime.exec is that it uses "SIGCHLD" and waitpid to clean up
after the created subprocess. Since frysk is also managing those kernel
interfaces a chash occures.
Instead the code should more directly use frysk.sys.Fork.exec or similar to
create the child process.

The method frysk.sys.Fork.daemon() would be best as it re-parents the process to
not be frysk.
Of course, this also has the disadvantage of not being able to determine when
the program fails to start.

Converted to use frysk.sys.Fork.daemon(). Now causes backtraces on initial
activation. This has been enumerated in bz #3927.
