I applies cleanly on the wip/rtnet branch, so I did test it and indeed it fixes
the issue.

I don't know the direction where you want to go with the cobalt functionality,
this change is IMHO badly needed as digging into one process should never
affect others.
However, there still is a difference to Linux behavior, namely that a periodic
timerfd will read the
count of expired events after continuing. The cobalt implementation will just
forget about them.
I suppose this hackaround is necessary so one-shot events aren`t dropped?
