LinuxThreads requires two signals. And if somebody (for Linux-2.0 compatibility) wants to write the POSIX.1b signal emulation using message queues we need another symbol.
Sooo, we need two people/groups. One writing the emulation of POSIX.1b signals using 1 signal and the other group who writes POSIX.1b signals for the kernel. I already have quite some code for the AIO implementation in user level so that it should be possible to use it as soon as the signals are available.
