lock Multiple locks

[JTTest1997]

I have a sequence that use 3 different equipment.

I use Locks all along my sequence because I am test 4 units in parallel.

To reduce test time I would like to start 3 threads simultaneously  for each devices. (Devices like Power Supply, NIDaq and spectrum)

But before lunching the 3 threads simultaneously, I want the 3 locks to be free to not having to wait to long for measurements to complete. 

I try to Pass an array to lock multiple locks but it doesn't seems to works as expected. Locals.loackArray

Locals.lockArray[0]="LockNiDaq", Locals.lockArray[1]="LockSpectrum",Locals.lockArray[2]="LockPS"

I solve my problem by locking with Array of locks, then launching my 3 threads and then releasing each lock.

It would be good to being able to unlock an Array of locks.
