When finished with a DTrace script that created some 2 MB
aggregations on a 128 CPU 5240, I noted that DTrace seemed
hung...

trussing it produced a long stream of:

ioctl(3, DTRACEIOC_BUFSNAP, 0x100111A58)        Err#2 ENOENT
ioctl(3, DTRACEIOC_BUFSNAP, 0x100111A58)        Err#2 ENOENT
ioctl(3, DTRACEIOC_BUFSNAP, 0x100111A58)        Err#2 ENOENT

Out of space? Something else? Seems as if retrying is pretty hopeless,
so why not just quit?
