Change 49563 by marcel at marcel_nfs on 2004/03/22 19:14:06

	Add td_tid to struct thread so that we can assign a thread ID to
	threads. This is needed by gdb. The kernel doesn't use thread IDs,
	so we need to assign them when we enter the debugger. Obviously
	you don't want to do that in the debugger, but I think that I'll
	end up wasting a lot of time trying to migrate the kernel to use
	thread IDs over process IDs.
