I got a similar situation as the TO except there's no more output. No responsiveness whatsoever. CTRL-Q won't resolve it either.

Tracing this vim instance just shows:

strace -p <vim-PID>
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=0, tv_nsec=10000000}, NULL) = 0
ioctl(0, TCGETS, {c_iflag=ICRNL|IXON|IXOFF|IUTF8, c_oflag=NL0|CR0|TAB0|BS0|VT0|FF0|OPOST|ONLCR, c_cflag=B38400|CS8|CREAD, c_lflag=ISIG|ECHOE|ECHOK|IEXTEN|ECHOCTL|ECHOKE, ...}) = 0
ioctl(0, TCSETS, {c_iflag=IXOFF|IUTF8, c_oflag=NL0|CR0|TAB0|BS0|VT0|FF0|OPOST, c_cflag=B38400|CS8|CREAD, c_lflag=ECHOK|ECHOCTL|ECHOKE, ...}) = 0
ioctl(0, TCGETS, {c_iflag=IXOFF|IUTF8, c_oflag=NL0|CR0|TAB0|BS0|VT0|FF0|OPOST, c_cflag=B38400|CS8|CREAD, c_lflag=ECHOK|ECHOCTL|ECHOKE, ...}) = 0
wait4(703012, 0x7ffc3b1270b4, WNOHANG, NULL) = 0

Ideas anyone?

Thx
