It's better to duplicate last lines from truss output & procstat output here:

===== truss output =====
clock_gettime(13,{1495402129.000000000 })        = 0 (0x0)
openat(0xffffff9c,0x80245b0a0,0x100601,0x1b6,0x7fffffffd580,0x801d13b20) = 3
(0x3)
fcntl(3,F_GETFD,)                                = 1 (0x1)
fstat(3,{ mode=crw-rw-rw- ,inode=8,size=0,blksize=4096 }) = 0 (0x0)
openat(0xffffff9c,0x8008bc804,0x100000,0x0,0xffff80080245c7d7,0x0) = 4 (0x4)
fcntl(4,F_GETFD,)                               

===== procstar output related to tar =====
75044 101901 bsdtar           -                mi_switch+0xbe sleepq_wait+0x3a
