The general feeling is that going straight to fine-grained locking is
just not achievable given the resources available..

Having biglock in -current allows work on the (very significant)
amounts of work needed on each MP platform (for TLB shootdown,
IPI/cross-calls, interrupt model changes, etc.,) to proceed in a way
at least partly decoupled from changes to the MI parts of the kernel..
