According to Eric Blake on 11/20/2009 7:15 AM:
>>> 	* signal.cc (nanosleep): Support 'infinite' sleep times.
>>> 	(sleep): Avoid uninitialized memory.
>> Sorry but, while I agree with the basic idea, this seems like
>> unnecessary use of recursion.  It seems like you could accomplish the
>> same thing by just putting the cancelable_wait in a for loop.  I think
>> adding recursion here obfuscates the function unnecesarily.
> 
> How about the following, then?  Same changelog.
