user mode exceptions

[Hartmut Birr]

Hi,

on a user mode exception, I get hundreds of lines like this:

(i386/exception.c:96) RtlpDispatchException()
Dumping exception registrations:
   (0x0065FFE0)   HANDLER (0x7C82CEAF)
   (0x7FFDF000)   HANDLER (0x00000000)
(i386/exception.c:96) RtlpDispatchException()
Dumping exception registrations:
   (0x0065FFE0)   HANDLER (0x7C82CEAF)
   (0x7FFDF000)   HANDLER (0x00000000)
(i386/exception.c:96) RtlpDispatchException()
Dumping exception registrations:

It needs a very large time, if ros does response again. It occurs on 
real hardware. Debugprints are going over a serial line.
