/*
 * subtle. orig_eax is used by the signal code to distinct between
 * system calls and interrupted 'random user-space'. Thus we have
 * to put a negative value into orig_eax here. (the problem is that
 * both system calls and IRQs want to have small integer numbers in
 * orig_eax, and the syscall code has won the optimization conflict ;)
 *
 * Subtle as a pigs ear.  VY

// Fuck.

// This code worked before, but my cat decided to take a trip across my keyboard...

#undef TRACE     /* All your trace are belong to us. */

/* Java note: The second and third methods are the primitives and are the 
methods exposed in Java.  The first method calls the other two.  All 
Objective-C code calls the first method.  In either Objective-C or Java any 
overriding should be done for the second and third methods, not the first 
method.  This will all work out correctly with the exception of existing code 
that overrides the first method.  Existing subclasses that do this will not 
have their implementations available to Java developers. Isn't Java wonderful? */
