But it doesn't actually work, it
just lock up dosemu in a non-TSC
mode unless the attached patch is
applied.

Well, there are either the combos
that are always reserved by some
WMs, and those can and should be
avoided.

User-defined combos is not something
we have to care about, that was not
what I mean.

The only disadvantage of it is that
it switches a scroll-lock led:)

And you'll probably never know what
other combos it already reserved
without you even asking it about:)
I think dosemu can avoid using those.
