did i miss the console cleanup crew?

i have a UML guest command line that uses con0=fd:0,fd:1
(or not, as this is the default for CONFIG_CON_ZERO_CHAN)

i launch new xterms using -- xterm -e '<guest cmdline>' &
(side note - can lock it w/o this too.) and users leaning on
the keyboard (most notably <enter>) while the new xterms pop
up and steal the window focus have experienced unresponsive
UML prompts.

no further keyboard input is processed...

uml_mconsole <id> reboot and things can be made better.
so the UML isn't locked up just the stdin....

i've tried to go thru stdio_init -> open_console -> line_open
to see if there was a likely place to drop a 'flush' of stdin
before we try attaching 0 -> 1 and 1 -> 0 (line_setup_irq)...
but i don't understand it all enough <frown>.

this is redhat 9 + SKAS - NPTL 2.4.20-31 host kernel
linux 2.4.26-3um guest kernel.

thank you.
