print 0 %ux as 0x0

more debugging

try to avoid calling notify on the "dumb" signals

add core dump and signal to status line

change md argument to number etc. (which acted only as a flag) to an actual flag. buffer underrun check in number add xdata file for exactly the addressed region save addr across opens

formatting

exit 9p on interrupt signal. should do better job here.

run 9c before 9a because gas doesn't exit with non-zero status when the file doesn't exist

update change file

use threadexitsall

print out signalled exits

add ulimit and umask as builtins

remove socket at exit

fix interrupt handling, add clumsy way to get at text buffer contents

finally got these working
