      CAUTION: Finally, coprocesses open up the possibility of "deadlock"
      between 'gawk' and the program running in the coprocess.  This can
      occur if you send "too much" data to the coprocess before reading
-     any back; each process is blocked writing data with noone available
-     to read what they've already written.  There is no workaround for
-     deadlock; careful programming and knowledge of the behavior of the
-     coprocess are required.

+     available to read what they've already written.  There is no
+     workaround for deadlock; careful programming and knowledge of the

    The following example, due to Andrew Schorr, demonstrates how using
 ptys can help deal with buffering deadlocks.
