* thread_pthread.c (native_sleep): cut the waiting time up to
100,000,000 because Solaris cond_timedwait() return EINVAL if an argument is greater than current_time + 100,000,000. This is considered as a kind of spurious wakeup. The caller to native_sleep should care about spurious wakeup. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32409 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
