Turbostat works by taking a snapshot of counters, sleeping, taking another snapshot, calculating deltas, and printing out the table. The sleep time is controlled via -i option or by user sending a signal or a character to stdin. In the latter case, turbostat always adds 1 ms sleep before it reads the counters, in order to avoid larger imprecisions in the results in prints. While the 1 ms delay may be a good idea for a "dumb" user, it is a problem for an "aware" user. I do thousands and thousands of measurements over a short period of time (like 2ms), and turbostat unconditionally adds a 1ms to my interval, so I cannot get what I really need. This patch removes the unconditional 1ms sleep. This is an expert user tool, after all, and non-experts will unlikely ever use it in the non-fixed interval mode anyway, so I think it is OK to remove the 1ms delay.
