Yes.  And it's actually easier than I thought.  Here's the pertinent 
quote from the Posix spec:

"If sleep() returns because the requested time has elapsed, the value 
returned shall be 0. If sleep() returns due to delivery of a signal, the 
return value shall be the "unslept" amount (the requested time minus the 
time actually slept) in seconds."

I don't know how I missed this the last time I read the spec--this is an 
issue I was aware of and wasn't sure how to solve efficiently.  I'm 
going to fix it in Tango right now :-p
