History
John Baldwin 9665592e2b According to the submitter, POSIX mandates that all interval timers are 
reset in a child process after a fork().  Currently, however, only the
real timer is cleared while the virtual and profiling timers are inherited.

The realtimer is cleared because it lives directly in struct proc in
p_realtimer.  It is in the zero'd section of struct proc.  The other timers
live in the p_timer[] array in struct pstats.  These timers are copied on
fork() rather than zero'd.  The fix is to move p_timer[] to the zero'd
part of struct pstats so that they are zero'd instead of copied on fork().

Note: Since at least FreeBSD 2.0 (and possibly earlier) we've had storage
for two real interval timers.  Now that the uarea is less important,
perhaps we could move all of p_timer[] over to struct proc and drop the
p_realtimer special case to fix that.
