When working with shared data in threading how do you implement
synchronization ?

There are a somethings you need to be careful with when using threads.
If two threads(e.g. the main and any worker threads) try to access the
same variable at the same time,you'll have a problem. This can be very
difficult to debug because they may not always doit at exactly the same
time. To avoid the problem, you can lock a variable before accessingit.
However, if two threads lock the same variable at the same time, you'll
have a deadlockproblem.

SyncLock x
'Do something with x
End SyncLock
