Commented Issue: Thread-safe event handling [1551]

Consider rewriting this:

if (this.ErrorOccurred != null)
{
this.ErrorOccurred(this, e);
}

Into:

var handler = ErrorOccurred;
if (handler != null)
{
handler(this, e);
}

I just applied you suggestion in 24900 commit but I still wondering whether I should use lock.
Closing it now.

Thanks,
