When we have multiple groups in an evlist, say:
$ perf stat -e '{cycles,instructions},{cache-references,cache-misses}' sleep 1
Performance counter stats for 'sleep 1':
343,134 cycles:u
249,292 instructions:u # 0.73 insn per cycle
15,556 cache-references:u
8,925 cache-misses:u # 57.373 % of all cache refs
1.000957550 seconds time elapsed
$
Then the perf_evsel instances for the two group leaders ("cycles" and
"cache-references") will have evsel->nr_members set to 2, while all the
evsel->evlist->nr_entries will be set to 4, so we can't use
evsel->evlist->nr_entries everywhere, as event groups need to be taken
into account.
But this probably requires us to audit at least the forced-group code,
where we want all of the events to be in a "group", to see them all in
the screen, one column for each, even knowing that they were not
necessarily scheduled to count at the same time by the kernel perf
subsystem.

Currently 10us delay is too low for many tests to succeed. It needs to
be increased. Also, many corked tests are expected to hit rx timeout
irrespective of timeout value.
- This patch sets 1000usec timeout value for corked tests because less
than that causes broken-pipe error in tx thread. Also sets 1 second
timeout for all other tests because less than that results in RX
timeout
- tests with apply=1 and higher number of iterations were taking lot
of time. This patch reduces test run time by reducing iterations.
