This patch fixes the poll bug that I found in -4.
The main change is that task switching is now done without the assistance
of the tracing thread. The reason this was done now was to fix the bug
that UML couldn't be ^Z-ed and bg-ed. If you don't immediately see the
connection between the bug and the fix, read the UML diary. All will
One bit of advice resulting from this: if anyone offers you a job that
involves understanding job control, scream and run away.
The patch is available at
