Xlib: Maximum number of clients reached

I've got a Sun Blade 100 running Solaris 8 "5.8 Generic_108528-13".

I've got plenty of file descriptors:
$ ulimit -a
core file size (blocks) unlimited
data seg size (kbytes) unlimited
file size (blocks) unlimited
open files 256
pipe size (512 bytes) 10
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 7893
virtual memory (kbytes) unlimited

I've got plenty of pty's (the problem is X clients, *not* strictly xterm
-- I can't open Star Office or the calculator app or anything).

I'm getting the old error:
$ xterm
Xlib: connection to ":0.0" refused by server
Xlib: Maximum number of clients reached
xterm Xt error: Can't open display: :0.0

Now I looked in the archives and I see there was (is?) a hard limit of 128
clients, but that 80 is around the practical limit, no info as to why.

Most of my clients are xterms, but I've also got a few small apps running
(xclock, xbiff, gaim, netscape, mozilla).

Total, I've got 69 client windows spread across 12 workspaces in CDE.

Questions:
1) Shouldn't I be able to get more than 69 client windows running? Does a
window occupying more than one workspace count towards multiples? In that
case, I've got 91 (the clock and biff windows occupy all workspaces).

2) Is the X version that ships with Solaris 8 still constrained by the 128
client max?

3) Is there any hope for me (either getting more clients or gaining back
my sanity and closing some windows occasionally)?

Thanks,
-Adam
