Prossibly, and let me guess.. "if the receiving process appears to be in a
"hung" state"
is difficult to determine? (Otherwise, I guess it isnt that difficult to
implement
as the rest of it is all there).

The only reason I hesitate to agree with you is the difference in the
RealizePalette
returns, one (wine) indicating 256 colors had to be changed, the other
(win2k)
indicating none had to be.  Maybe this is a side effect of our x11drv
palette
implementation, but it still is slightly worrying?

Whats the best way to progress this? I can continue plodding by commenting
out the
whole line, so shall I just raise a bug for it?
