I haven't thought through it entirely but basically a new timer_t type
which would be typdefed as a long long int.  A function to set the
timer for some number of seconds in the future, and a function to
check if the timer has gone off.  Perhaps a wait for timer function
too.  It would be pretty trivial, but we've reimplemented this logic
all over the code and are bound to make mistakes like this as it's not
super clean.
