This are times counted with TEST_LOAD_EL=yes. I've committed
2d0853f62ac65f974f25887f69506bfe923bf14b, which changes the defaults
(see also README). Rerunning the tests shall show improved timings.

I don't want to set these tests as expensive, because they check
essential Tramp features. But as said the other message, I will work to
make them slimmer.

I have no opinion on this. Glenn? Eli?

Best regards, Michael.
