Threads don't have signal queues. POSIX specifies that a process has a *global* list of pending signals and a *thread-local* list of currently blocked signals. A correct implementation could iterate over the list of all threads of a process, whenever either a new signal arrives or a thread mask is changed. This is not the behaviour Linux implemented for ages. Joerg
