Hmm... I didn't even know about the strtok() function.  Oh here's why -
from the man page:

BUGS
       Never use these functions. If you do, note that:

              These functions modify their first argument.

              The identity of the delimiting character is lost.

              These functions cannot be used on constant strings.

              The  strtok()  function  uses a static buffer while
              parsing, so it's not thread safe. Use strtok_r() if
              this matters to you.

Even the man page for strtok() says not to use it.  Now I know why I never
heard of it.  But I can't see any difference between strtok() and my
little getword() function, other than strtok() uses a static buffer and
getword() doesn't.  That should fix the threadsafe problem.
