Why do we have this as a user-selectable option? It should be on by
default on 32 or 64bit.
History maybe ? In the early days it was a bit "experimental" (we
had a
couple of issues that popped up with some thread flags not being
properly recovered etc...). Nowadays, I agree it should not be an
option.
for some reason I felt that it was pretty much required on ppc64 when
I did the port over to ppc32.
Do we think we want to poke Paul to get this in for v2.6.26 so we can
get it some more testing on all the ppc32 systems?
