Do POSIX subcommittees ever look at each others' work#

Do POSIX subcommittees ever look at each others' work? The implementation of interrupt-thread is made more complicated by it not being possible to sigqueue a thread, and likewise not being possible to pthread_kill and pass any data to the thread being signalled. So, we need something held per-thread to indicate what code to interrupt it with, and then some stupid locking regime so that it can be interrupted from two other threads at once without something weird happening. OK, it's not rocket science, and scalability arguments probably don't matter too much as we don't really expect interrupt-thread to be used in expected-to-be-fast code anyway. It's still annoying, though.

I still haven't bought a new laptop; I'm still trying to figure out whether I actually need one or not: so far, the only requirement I've identified is to be able to IRC in front of the TV from time to time, and that's not pressing really. I did also wonder for a while whether I could use a PDA, but after thinking a while longer, maybe I can get away with a text file instead.
