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