Thead.Abort should be avoided.

Added by:Peter Ritchie

There's many reasons not to use Thread.Abort and ThreadAbortException

On certain platforms (like x64 and IA64) the abort can occur before Monitor.Enter and a try block (even with lock/SyncLock), leaving the monitor orphaned.
The ThreadAbortException can occur in 3rd party code not written to handle thread abort.
The thread can be aborted while processing a finally block in .NET 1.x
Uses exceptions for normal control flow logic.
Asynchronous exception can interrupt modification of shard state or resources, leaving them corrupted.
