I am somewhat unsure myself reading through the commit log message
again. It says that this "lays the groundwork" to solve this issue and
mentions that each platform and architecture's implementation of the
internal runtime┬Ěnanotime() *should* be modified (with linux/x86 shown
as the only modified and tested platform) to use monotonic time. The log
short message says "runtime: use monotonic clock for timers (linux/386,
linux/amd64)" however.

Looking at the code changes, the assembler for runtime┬Ěnanotime()
on amd64 has been changed as well though. Since AFAIK, if it is
correctly implemented, your issue would not exist I think you should
ask the golang-nuts[0] mailing list about the issue (maybe mentioning
the commit and the issue 6007 as well). I can do it if you don't want
to but I will be travelling (accidentally to dotGo in Paris :-) ) so it
may take a while.
