Oh, in that case maybe the other code that does the "rd %pc" version should be switched to using sethi/or sequences. (Or maybe it is already in places where there is no good scheduling.) >I'm pretty sure using a software interrupt is the best solution.

In my case, I will have to go work out how the software interrupts work, so as to make sure I don't step on some other interrupt. I'll probably get a chance to try sometime Monday or Tuesday though -- actually I'm working with other folks and they'd be doing the "try" part -- as I have a pile of other work I have to get done this weekend and Monday.
