These other complaints are perhaps QoI issues, but not major bugs; an application has no basis to assume it's safe to let untrusted processes map its synchronization objects. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
