Problem:

Edition of Specification (Year): 2004

Defect code :  3. Clarification required

http://www.opengroup.org/onlinepubs/009695399/functions/nanosleep.html#tag_03_402
The behaviour of nanosleep is unclear if the rqtp parameter specifies a value 
of zero. If zero is specified, does nanosleep do nothing (ie. not suspend the 
current thread and return 0) or does it guarantee to suspend the thread for the 
minimum (sleep resolution) interval?

Action:

Provide clarification on the behaviour and return value of nanosleep() if rqtp 
specifies a value of zero.
