  Log:
  Pass a thread argument into cpu_critical_{enter,exit}() rather than
  dereference curthread.  It is called only from critical_{enter,exit}(),
  which already dereferences curthread.  This doesn't seem to affect SMP
  performance in my benchmarks, but improves MySQL transaction throughput
  by about 1% on UP on my Xeon.
