+Set the scheduler locking mode.  It applies to normal execution,
+record mode, and replay mode.  If it is @code{off}, then there is no
+locking and any thread may run at any time.  If @code{on}, then only
+the current thread may run when the inferior is resumed.  The
+@code{step} mode optimizes for single-stepping; it prevents other
+threads from preempting the current thread while you are stepping, so
+that the focus of debugging does not change unexpectedly.  Other
+threads never get a chance to run when you step, and they are

+@samp{until}, or @samp{finish}.  However, unless another thread hits a
+breakpoint during its timeslice, @value{GDBN} does not change the
+current thread away from the thread that you are debugging.  The
+@code{replay} mode behaves like @code{off} in record mode and like
+@code{on} in replay mode.
