  SVN rev 193963 on 2009-06-10 22:54:20Z by jkim
  
  Catch up with r193750 (OsdSynch.c locking changes):
  
  - Preallocate some memory for ACPI tasks early enough.  We cannot use
  malloc(9) any more because spin mutex may be held here.  The reserved
  memory can be tuned via debug.acpi.max_tasks tunable or ACPI_MAX_TASKS
  in kernel configuration.  The default is 32 tasks.
  - Implement a custom taskqueue_fast to wrap the new memory allocation.
  This implementation is not the fastest in the world but we are being
  conservative here.
