=== *Description* ============================================================
Following construction sometimes ends with wrong return value.
56 echo $op | grep rand 2>&1 >/dev/null
57 if [ $? = 0 ]; then
58 randseq="rand${SEED}"
59 else
60 randseq="seq"
61 fi
Sometimes, the given result is "rand..." even when there is no "rand" word in
$op. This can be demonstrated with TSufs/SnapShots/Func test case which
excercises shown code quite often.
As it happens only sometimes, I suppose there is an race-condition in handling
return value from a child process.
