X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=ce7d72596c57386c493969cc56546c7aba2e1049;hp=ce7d72596c57386c493969cc56546c7aba2e1049

fix cancellation failure in single-threaded programs

even a single-threaded program can be cancellable, e.g. if it's called
pthread_cancel(pthread_self()). the correct predicate to check is not
whether multiple threads have been invoked, but whether pthread_self
has been invoked.
