This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:
int gettimeofday(struct timeval *restrict tp, void *restrict tzp);
Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.
While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

1. If fgets fails, don't go into an infinite cpu-intensive loop. Instead,
check to see if the terminal still exists, and sleep(1) otherwise.
2. When we check to see if the terminal still exists, make sure we're not
mislead by EINTR. This could have been a security issue, but fortunately
the current implementation of tcgetattr doesn't EINTR.

/usr/bin/lock can be used to lock a terminal much like xlock does
for your X-windows session. Problem is, /usr/bin/lock cannot lock
your terminal indefinately. Rather you must specify a timeout
value, after which, your terminal is unlocked and become unsecured.
I have added a ``-n'' no timeout option to /usr/bin/lock
Currently the only way to get this functionality is to use a huge
timeout value and hope it is long enought (in time). This method
also requires you to know the maxium number of minutes you are
allowed to specify.

automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
