Tracking issue for unimplemented syscalls

[maxbla]

There are a boatload of syscalls dealing with time. It would be nice if this library dealt with all of them that use relative time, like timeouts. Absolute time, like a file's last modified time are more annoying to deal with, but you're already doing it some.

Probably necessary

• [ ] times
• [ ] futex
• [ ] timer_settime
• [ ] timer_gettime
• [ ] clock_settime
• [ ] clock_gettime
• [ ] rt_sigtimedwait
• [ ] mq_timedsend
• [ ] mq_timedreceive
• [ ] recvmmsg
• [ ] pselect6
• [ ] ppoll
• [ ] epoll_wait_old???
• [ ] epoll_wait
• [ ] epoll_pwait
• [ ] io_getevents
• [ ] semtimedop

Stretch goals

• sched_rr_get_interval
• utime
• utimes
• adjtimex
• settimeofday
• utimensat
• timerfd_settime
• timerfd_gettime

This issue assumes you only care about Linux support - other Unixes don't have all these syscalls.
