It is required for async cancellation to work. Fix PROC_LOCK leak in linux_tgkill when signal delivery attempt is made to not linux process. Do not call em_find(p, ...) with p unlocked. Move common code for linux_tkill() and linux_tgkill() into linux_do_tkill(). Change linux siginfo_t definition to match actual linux one. Extend uid fields to 4 bytes from 2. The extension does not change structure layout and is binary compatible with previous definition, because i386 is little endian, and each uid field has 2 byte padding after it.
