Bruce Evans fb717773e7 Fixed locking bugs in rev.1.346: ... (1) Don't attempt aquire the non-recursive lock sio_lock recursively. Doing so caused unbounded recursion in some setups. E.g., if DDB, BREAK_TO_DEBUGGER and WITNESS are configured; if the debugger is entered using a break, then WITNESS will actually detect the invalid recursion and will add to it attempting to print a message about it. (2) Don't use sio_lock before it has been initialized. The old check (sio_inited != 0) didn't work when sio_inited was boolean because sio_inited was set too early, and became just wrong when sio_inited was changed to a tri-state variable in rev.1.348.
