No, apparently we couldn't. Doing a further investigation on the kernel sources, the only mention I found to SIGSWI (not counting the declaration itself) is on the file , some apparently odd ARM-based (RISCOS) OS which uses this communicate with its emulator somehow. It is called Arthur OS, and I don't think we support it in any way. So, after seeing this, I think we shouldn't care about this until we choose to support the OS. > Second, the new enum seems like dead code.
