then it is already racy - at least for multiple users sharing the same target
box.  But it is IMO racy even on fast enough clicking in Eclipse by a single
user.

To remove the racy case some kind of backward compatibility with current
setups has to be broken.

If you want to keep the racy behavior for users (for its other benefits) I can
propose a patch fixing only the testsuite and not affecting the normal
gdbserver executions by users in any way.
