From 7e74a73499059263212048ad989facae5500d230 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 8 May 2017 16:13:08 +0200 Subject: blockjob: strengthen a bit test-blockjob-txn Unlike test-blockjob-txn, QMP releases the reference to the transaction before the jobs finish. Thus, qemu-iotest 124 showed a failure while working on the next patch that the unit tests did not have. Make the test a little nastier.
