I don't mean to be a pain, but this patch does not fix the bug I
reported. It is still occurring on i386 and ppc64 (and proc_pid_flush
now generates lots of might_sleep warnings).
kernel BUG in migration_call at kernel/sched.c:4044!

Hopefully, I should have time to perform a bisection search this
weekend.
