     I found that in file nojobs.c there is wait() loop, if it gets
     error from waits, it prints it out and then waits again. If
     error is No Child Process ,ECHILD it sill tries wait again
     infinitely. The fix is that break loop in ECHILD.
     here is diff.

	The bug was not in xterm , it was in rlogin. The rlogin
	lost all lines in buffer when IXON flag was changed by 
	ioctl call. I do not know does this bug exist in other
	rlogins that 386/ix one. 
	Fix: use stty -ixon in rlogin sessions with 386/ix

	After these two fixes bash seems to work fine in 386/ix 2.0
	Now i use it in normal use.
