820682 - DMD: Tweak stress mode

Status: RESOLVED FIXED

(Core :: DMD, defect)

Description

[Nicholas Nethercote [inactive]]

The forthcoming patch tweaks stress mode:

- Always run it with --sample-mode=1.

- Dump the output.  This gives greater coverage (e.g. it demonstrates if
  dumping is slow), and it's often useful to be able to see the memory stats.

Call this OpenFileTestMode or something?  Maybe add an assertion that we don't
call this in normal mode?
