Please don't overexagerate. The logs are written only if tramp-verbose
is greater than 6, which is an exception. And there is no additional
traffic due to this verbosity.

Using mutex is work in progress. When it turns out not to be applicable,
I'll remove it from Tramp.

The Tramp version bundled with Emacs doesn't use this code
yet. Therefore, I don't see any reason to write documentation about.
