I have to believe that tests socket-14.* and socket-15.* are
intended to test important additions to [socket] that came
in with Tcl 8.6.

In practice though, I am forced to -skip these tests because
they take ***forever*** to run and they fail in normal environments
I test in frequently.

The best tests both pass and fail quickly and only fail when something
is actually wrong.  These tests do not measure up.
