-Change unconditional aquisition of Giant to only pickup Giant if the vnode
 for the controlling tty resides on a non-mpsafe file system.
-Pickup Giant around executable vnode reference counting operations only if
 the executable resides on a non-mpsafe file system.
-If this process is being traced, pickup Giant for trace file reference count
 operations only if it resides on a non-mpsafe file system.
