No, I have the fill column to be the standard 72.  The problem is due to 
the argument of \intertext{} being small. 
The lines are expected to be small in presentations (slides).  Hence 
this approach is generally not useful for slides.
Longer sentences do get broken in my case also.  But there is some other 
problem in this case: the following equation may not start on a new 
line.  For example, I got the following formatted source:

\item Then the characteristic equation of $A$ is given by \pause
 \begin{align*}
   z^n + a_1 z^{n-1} + \cdots + a_{n-1} z + a_n & = 0 \pause
   \intertext{As per Cayley Hamilton's theorem, a matrix satisfies
     its own characteristic equation: \pause} A^n + a_1 A^{n-1} +
   \cdots + a_{n-1} A + a_nI & = 0 \pause
 \end{align*}
\item Evaluate the desired characteristic polynomial

There is an easier approach for the same end: create a blank line just 
before \intertext and comment the blank line (align environment does not 
like blank lines).  I am not happy with this solution, though, because 
it makes the source bulky and I am not comfortable with too many blank 
lines within a paragraph.

Thanks for all the help.
