Does the sparc sigemt_handler need to arch_skip_next_instruction when
fielding a pseudo-atomic-interrupted trap?

Stack overflow handling.

New function-end breakpoint support.

The scheduler needs to know that some instructions can cause a pipeline
stall even if they don't need nops.

The indentation when tracing functions that tail-call other functions is
real strange.

lisp::get-group-or-user-name should use getpwent so it works with the
yellow pages.

flush-output-buffer before doing a file-length.

Miles' fd-stream mods:
 - /dev/tty gets left open even if we decide not to use it.
 - merge the patch he sent.


;;;; HPPA stuff.

Figure out how to use the immediate offset in ble/be to not have to compute
the full raw-pc in LIP.


;;;; Pathname fixes

(unix-namestring foo nil) should ignore non-existant directories.

permission denied errors inside of unix-namestring should be signaled.



High priority:

GC/interrupt lossage:
    - LIP doesn't get fixed if it points to the raw function address and
    nothing else points to the function or code object.  We need to see if
    any regs hold a symbol with the LIP for it's raw function address.
    - LIP will get clobbered even if it doesn't point to the middle of an
    object.

Put something in interrupt.c to detect bogus csps, alloc ptrs, etc?

OOB during a without-interrupts looses.

Hemlock key events stuff.



sparc stuff:

/afs/cs/mach/src/kernel/latest:   Latest machine independant sources.
/afs/cs/project/systems-berman/src/kernel/latest:  Latest SPARC sources.

Make taddcctv safe.

Fix various places blting code is used to use ld [reg+reg] addressing so
that only one reg needs to be incremented each iteration.



Low priority:


the debugger should tell you if interrupts and/or gcing is turned off.

defmacro:
    fix dotted &rest lists



Big projects:


Rewrite sequence stuff.

Debug info for assembly routines.
