[PATCH] make ITIMER_PROF, ITIMER_VIRTUAL per-process
POSIX requires that setitimer, getitimer, and alarm work on a per-process
basis. Currently, Linux implements these for individual threads. This patch
fixes these semantics for the ITIMER_PROF timer (which generates SIGPROF) and
the ITIMER_VIRTUAL timer (which generates SIGVTALRM), making them shared by
all threads in a process (thread group). This patch should be applied after
the one that fixes ITIMER_REAL.
The essential machinery for these timers is tied into the new posix-timers
code for process CPU clocks and timers. This patch requires the cputimers
patch and its dependencies.
