   The attached patch tries to fix a number of bogus failures when the
   testsuite is being run on a very slow target (such as a simulator).

   Instead of trying to match the output using a single pattern, it matches
   the output incrementally.

This is a good idea!  I was talking with HP folk about adding some sort
of special test procedure for large and complicated output, and here
you've actually implemented something... The procedure itself should go
in lib/gdb.exp, so that other files can use it too.

   + # SENTINAL: Is the terminal pattern indicating that output has finished=
   =2E

"sentinel" not "sentinal"

   +     while { ${index} >=3D 0 && ${index} < [llength ${list}] } {

What's the "3D" all about?
