Thank you dslake for diagnosing and fixing a race condition in OGS1SecureInventoryServer (mantis #3483). The provided patch was slightly modified to narrow the locking scope to smaller portions of the functions. Applied the same locking to HGInventoryService, which suffered from the same race condition.
