MC BUG: 100% CPU usage if terminal hanged

[Yuri <yuri tsoft com>]

It's another bug which can be problematic:

Description:
mc is used through network in telnet or ssh.
If network link dies but terminal is still running
mc often gets to 100% CPU usage.

Versions: mc-4.5.55, FreeBSD-4.6 and previous.

Solution: mc should never loop w/out select on
appropriate file descriptors. IO descriptors in this case
I guess.

Yuri.
