Looking at the implementation of sleep, this strongly suggests that some
other part of your program is interrupting the sleeping thread. As Vijay
suggested, you could program around this. This would give you the sleep
behavior you want, but perhaps mask a real (performance) problem in the
rest of your program you should be fixing. I'd try to get a
debugger/logging printfs into the Java/C++ implementations of Thread.sleep
and see if there are hints as to where the interrupts are coming from.
