- Fixed deadlock in xsi_sem_undo - RecordUndo - Fixed issue in xsi_sem_undo: if the semaphore set does not exist anymore, ignore the request but do remove the process from the sUndoList, which wasn't previously done. - free() in ClearUndos was called with interrupts disabled - when a semaphore set ends to exist, remove all it's sem_undo request as it's ID will be reused in the future. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26727 a95241bf-73f2-0310-859d-f6bbb57e9c96
