The Single Unix Specification provides that:

"An XSI-conforming implementation provides each process with at least three
interval timers ... ",

so it looks as if it is a process resource.  Which thread receives the
signal generated on expiry of the relevant time has been the subject of
earlier postings (POSIX does not specify this if the signal is unblocked to
more than one thread).
