server.update(int timeout) returning after incorrect timeout.

There's a "bug" whereby the server.update() method might take longer to return than specified.

E.g. a call of server.update(10) may take 25ms to return.

This issue is caused because of the way in which a workaround has been implemented for an issue with NIO.

The fix is very straight-forward:

Replace this code, in **Server.java**:

_// NIO freaks and returns immediately with 0 sometimes, so try to keep from hogging the CPU.
long elapsedTime = System.currentTimeMillis() - startTime;
try {
if (elapsedTime < 25) Thread.sleep(25 - elapsedTime);
} catch (InterruptedException ex) {
}_

with :

_// NIO freaks and returns immediately with 0 sometimes, so try to keep from hogging the CPU.
long elapsedTime = System.currentTimeMillis() - startTime;
try {
int targetDuration = Math.min(timeout,25);
if (elapsedTime < targetDuration) Thread.sleep(targetDuration - elapsedTime);
} catch (InterruptedException ex) {
}_

This ensures that, even if NIO "freaks out", we:

1. Still avoid hogging the CPU
2. BUT also avoid sleeping longer than the specified timeout

I have built and tested this locally, and it works, but not sure how to go about submitting it.
