init()

static unsafe void IKVM.Java.Externs.java.lang.UNIXProcess.init ( )

static

Implements the native method 'init'.

We save and load the old SIGCHLD handler between calls to prevent Java from overwriting the .NET handler. This isn't thread safe but should suffice since it's limited to static initialization.
