O'Brien said he would import the newest library. I first inquired about tweaking regex(3) maybe a month before Usenix. O'Brien said he planned to replace it, so I'd better keep my hands off. I continued researching regex implementations, as I have another project requiring me to write one. After Usenix, I contacted O'Brien again, and he said he missed the chance to talk to Spencer, and the new library would possibly not be merged back into 4.x, so I might as well go ahead and do my changes (they don't break any API/ABI, and require no recompilation of applications). Meanwhile, I sorely missed regex's test suit. On one hand, it makes it very difficult to hack the code. On the other hand, there are places in the code that refer to that test suit to explain bugs they are working around, so their absence makes the code more difficult to understand. For this reason, I decided to import it. -- Daniel C.
