>Environment:

3.0-BETA/RELEASE, using vi against a file in the local FFS file system
/usr.  X-windows using xterm, XiG's X server for notebooks.

>Description:

When resizing an xterm and using vi, once in a while I get:

ex/vi: Error: tcsetattr: Interrupted system call

This kills vi.  This is not good.  I believe I have observed this both
in command and edit modes.

>How-To-Repeat:

Start editing a file.  Now resize your xterm.  This does not always
appear to happen -- in fact, only infrequently.  I'm not sure if there
is a correspondence to the size of the file being edited.  I am unable
to repeat this consistently, but it has happened at least a few times 
in the past few months.

>Fix:
	
I'm on the road, so can't check the source or see if there is already
a PR in for this.  However, I'd guess that something in curses/ncurses/
whatever vi uses doesn't wrap a syscall in a check for EINTR, and this
results in vi terminating from an error it does not expect.
