[ Upstream commit 69b352927885b17f03d3ee4ee38f580699af107a ]
The thloop is similar to noploop but runs in two threads. This is
needed to verify perf record --per-thread to handle multi-threaded
programs properly.
$ perf test -w thloop
It also takes an optional argument to specify runtime in seconds
(default: 1).
