In directory netbsd1:/var/slash-tmp/cvs-serv14857

Modified Files:
      Tag: mrg-vm-swap2
        vm_swap.c 
Log Message:
It's perfectly okay to wait when adding/removing swap devices, so no fixed
extent maps are necessary.
Use a NOCOALESCE map to manage the per device block maps. In that case,
extent_free() will always return, while we let the swap pager deal with
allocation failures. Thus, no fixed extent maps here either and we can
do away with `nswapmap'.
