When I run screen, either under an xterm (88x61) or console (at either 80x25 or 132x50), top shows that screen is consuming almost 100% CPU, and most of that in system mode. Here's the relevant bits of the top output after running screen with one window containing an idle shell process for several minutes: CPU states: 11.2% user, 0.0% nice, 88.4% system, 0.4% interrupt, 0.0% idle Mem: 72M Active, 114M Inact, 34M Wired, 35M Buf, 29M Free Swap: 512M Total, 512M Free PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 83514 dragon 64 0 1920K 1616K RUN 6:25 98.93% 98.93% screen 321 root 10 0 45840K 45588K wait 2:10 0.00% 0.00% ruby16 176 root 2 0 39464K 38852K select 0:03 0.00% 0.00% XFree86 66563 dragon 2 0 2520K 1680K select 0:03 0.00% 0.00% ppp 83553 dragon 28 0 2044K 1220K RUN 0:00 0.00% 0.00% top That's everything that is either RUNning or has non-zero TIME. AFAIK, screen shouldn't be doing any I/O, because nothing in its window is changing. Similar behavior is not observed under Solaris with screen 3.07.06, nor under Linux (RH7.0, when I still used that.) Google hasn't turned up anything interesting either. So what's going on? ===== C.
