: block in detach until all references to softc have gone out of scope.

One thing to keep in mind is that if detach doesn't return for a
while, it may cause weird things to happen on a battery level or other
urgent induced suspend.  The way the current old pccard code does a
suspend is to detach the device.  The BIOS will force the shutdown if
the machine doesn't respond within 30 seconds to the suspend request
by suspending the machine.  At least APM seems to mandate this
behavior (well, it allows the BIOS to go ahead with an urgent suspend
if the host OS doesn't respond quickly enough).
