So it would NOT be ``exactly like "go"''.
Providing both a "go" and a "jump" command which differ just in cahce
handling seems broken to me. If you want to add such a feature, then
I recommend to do it as part of "go", but make it optional, i. e. in-
troduce a new optional argument to the "go" command, something like
go [ -cache={off,d-off,i-off,on,d-on,i-on} ] addr [ args ... ]

There is more procvessors in this world than just Blackfin, and
others *do* enable interrupts, etc. It is important to me that
implementations behave the same no matter which architecture you are
using.
