Move from AthReentrantAlg back to AthAlg (ATLASRECTS-5813)
Hi,
as discussed in ATLASRECTS-5813, the MuonCombinedInDetExtensionAlg derives from AthReentrantAlgorithm but uses (further down the call chain) the MuPatHitTool that has a mutable cache of pointers to-be-deleted and the end of the event. This causes the crashes observed in ATLASRECTS-5813. Moving back to AthAlgorithm should fix those until the MuPatHitTool is fully thread safe.
Best, Nico
