I'm still unsure what BASH_XTRACEFD trick you mean.  AFAICT we don't
play any tricks with it to make '-x' work properly, and indeed '-x'
tracing works properly even without BASH_XTRACEFD (and to achive that
we did have to play some tricks, but not any with BASH_XTRACEFD;
perhaps these tricks are what you meant?).

But then the actual issue is the unnecessary evaluation of the prereq
even when the test framework could know in advance that the test case
should be skipped anyway, and the trace from it is a mere side effect,
no?
