+ * single-stepping; it prevents other threads from preempting the current thread while you are stepping, so

+ * 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.
