/**
*
* -gdb-set scheduler-locking [on|step|off]
*
* Set the scheduler locking mode. If it is off, then there is no locking and any thread may run at any time.
* If on, then only the current thread may run when the inferior is resumed. The 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 only rarely (or never) get a chance
* to run when you step. They are more likely to run when you `next' over a function call, and they are
* completely free to run when you use commands like `continue', `until', or `finish'. However, unless another
* thread hits a breakpoint during its timeslice, gdb does not change the current thread away from the thread
* that you are debugging.
