Gets a value indicating whether the global lock should be used.
Returns
true if the global lock is to be used; otherwise, false. The default is true.
Remarks
The global lock is always used if the trace listener is not thread safe, regardless of the value of UseGlobalLock. The IsThreadSafe property is used to determine if the listener is thread safe. The global lock is not used only if the value of UseGlobalLock is false and the value of IsThreadSafe is true. The default behavior is to use the global lock.
