Are you talking about a standard Linux signal. In essence you should
avoid the use of signals in threads. In Linux, threads before the 2.6
kernel are not fully POSIX. In 2.6, Linux uses NPTL (Native POSIX Thread
Library). There is a thread signal paradigm that you could use in some
contexts. (I'm out of the door and have meetings all day and evening).
