  19 # These tests can generate large amounts of output, which can cause gdb to be
  20 # slow in two different ways:
  21 # - it takes long before the command starts producing output
  22 # - it takes long to print all the output
  23 # We can prevent timeouts due to the latter using exp_continue, but for
  24 # the former that doesn't work.  There we use with_timeout_factor instead.
