<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I am personally not conveinced the need for changing from usleep to nanosleep in this particular instance. IOW, usleep is sufficient in this case to warrant a change regardless of when that system call was made available...</pre>

usecSleepTime.tv_nsec = usecSleepTime.tv_nsec << 1;</pre>

1. ktimezone. Include a comment with the real use of refCount.
2. klocale_kde. From 469 queries to paths.end() to 1 (from 0.01% to 0% in callgrind)
3. netsupp. Remove a memory leak.
4. ksharedDataCache. Change the obsolete usleep (since 2001 or before) to nanosleep.</pre>
