This is required to work around a LOR with the socket code which results in an easy reproducible hard lockup with debug.mpsafenet=1. This commit does *not* fix the LOR, but enables us to do so later. The missing piece is to turn the filter locking into a leaf lock and will follow in a seperate (later) commit.
