Not completely implausible, but a) why isn't this seen on basically
every machine with software TLB? b) why does -local- GDB, which is
presumably doing much less work than gdbserver + network stack, not fail?

a) I don't know.... very odd.

b) gdb is big.  It probably touches far more pages (via library calls)
than gdbserver.  The network stack is also big, but it's probably more
localized too.

Niceing down the host also makes sense because if the PC is being slow
then the target may go off and run other things while between setting
the breakpoint and getting the 'go' command.

Can you grab a snapshot of the TLB before and after setting the breakpoint?

Or; probably more relevant, before and after the page copy?
