It depends on the login shell. For example, ksh sets TMOUT
to the system-defined value (often 7200) when it leaves
.profile. Thus, if your user's login shell is ksh, put in
/etc/profile the lines
    TMOUT=0
    # or any value different from the system-defined value
    export TMOUT
    # so your program can examine it
    readonly TMOUT
    # so the user can't change it at the start of .profile
and then have the program check the value of TMOUT in env.
