In umbraco.cms.businesslogic.web.Access, method IsProtected() calls IsProtectedInternal() within a read-lock but IsProtectedInternal does something like
if (CheckedPages.ContainsKey(DocumentId) == false) CheckedPages.Add(DocumentId, isProtected);
Which is prone to a race condition. Have witnessed exceptions being thrown by the hash table because of duplicate entries. Shouldn't we use a write-lock?
Assigning to Shannon who modified the code with c309e18f13e9579dbd2baef1ff2ca4633bda19e0 in march.
