4f2ac1b76b Working on better handling of multithreading in general 
and core dumps in particular.  See notes:

new types: register is something that when dereferenced gives you
	the registers.  the Ureg is no longer mapped at 0.
	refconst is something that gives a constant when dereferenced.

new builtin register("AX") creates register values
new builtin refconst(0x123) creates refconst values

new builtin var("foo") is equivalent to the variable foo
	(it returns foo but can also be used as the lhs of an assignment).

new acid function getregs() returns a list of the current values of registers.
new acid function setregs() sets the current registers to those values.
	note that getregs and setregs operate on register locations, not the
		register values themselves.
new acid function resetregs() sets registers to register("AX"), etc.
new acid function clearregs() sets all registers to constant -1.
the default register settings are as in resetregs(), not small numbers.

new acid variables coretext, pids, systype, corefile, cmdline.

new behavior: local variable lookup, stk, etc., use the acid values of registers
	(*PC, *SP, and so on), so the thread support code can change the context
	completely.

unary + is applicable to more data types and prints more often.

a0e8d02d09 Apparently SuSE 9.1's X distribution uses even bigger 
buffers than the standard ones.  64kB appears to be enough
for a stack in that case, but let's just go nuts and make
the stacks enormous, so that it takes a few more doublings
of X's stack needs before we run into this problem again.

The VM system should take care of not actually using most
of the memory anyway.

e9dbe11dbf don't rfork(RFNOTEG) because then you lose 
the ability to read from the console.  damn.

also, handle case where child exits before
fork returns in parent.  have to record that
sigchld was seen and then run the handler later.
