Simple question:

        Can channels on different pipes share PFCHAN_SWAPBUFFERS_HW even
        when their pipes are not genlocked?

I'm trying to isolate and reproduce an intermittent problem. Sometime my
program will complain about 'swap buffer failed'. It looks like this
message is printed from the GL itself - not from Performer.

I'd like to leave the following statement unchanged whether or not the
pipes are genlocked:

        chan[0]->setShare(PFCHAN_SCENE | PFCHAN_SWAPBUFFERS |
                          PFCHAN_SWAPBUFFERS_HW | PFCHAN_APPFUNC);

It is possible that this statement is causing the 'swap buffer failed'
problem?

Any opinion?
