I'm trying to get Performer1.2 to run in multipipe, multiple channel mode
when using the Triple Keyboard Option on my client's 3-pipe RE2.
That is, when running three X servers as :0, :1 and :2 instead of one
X server as :0.0, :0.1 and :0.2.

In perfly, I've modified the InitPipe function to call pfInitPipe three
times with a separate function for each; that function calls XOpenDisplay
with a different display string.

The command line is "DBG/perfly.DBG -x -M 1 -c 3".

I'm running IRIX 5.3.

When I run in non-TKO mode and the display strings are :0.0, :0.1 and :0.2,
it works fine. When I run in TKO mode and the display strings are
:0, :1 and :2, it fails with this stack trace when it tries to open the
second pipe:

Am I doing something wrong, or is this a limitation of Performer1.2?
If the latter, will it be addressed by Performer2.0?

Thanks,
Dan
