Comment 10 Allon Mureinik 2015-06-18 13:35:59 UTC 
Should be a non-issue in 3.6.0.
Moving to the scale team to verify.
Comment 12 guy chen 2016-04-14 07:31:57 UTC 
Verified

Was tested on VDSM 4.17.25, VDSM stayed up and did not restart during the procedure. 

Steps that where Reproduced:
1. created iscsi pools with 3 domains 100G each
2. created a wipe=true template (1GB disk)
3. created 3 pools from the template with 50 vm's on each pool
4. detach and remove the vm from each pool without waiting for previous pool to be deleted.
