How do you restore a DB to Multi-User mode when deadlocked by a sys process I have a database that is stuck in Single User mode after a failed restore process. I have checked the sysprocesses table and none of the processes have spid > 50. They are all sa processes. Using the following code returns a deadlock that I can not seem to clear:

ALTER DATABASE myDatabase SET MULTI_USER with NO_WAIT


Besides restarting the SQL Server and then spamming the Alter statement, is there a way for me to pull this out of single user mode? Thanks in advance for any help you can provide.
Apart from what Shawan referenced, another option is to use DAC ADMIN:ServerName
then issue below command (note that I am not using NO_WAIT)
ALTER DATABASE database SET MULTI_USER with rollback immediate

From BOL :

ROLLBACK AFTER integer [SECONDS] | ROLLBACK IMMEDIATE
Specifies whether to roll back after the specified number of seconds or immediately.
NO_WAIT
Specifies that if the requested database state or option change cannot complete immediately without waiting for transactions to commit or roll back on their own, the request will fail.
