This eliminates the edge case where the grow thread would not be able to create a new area because no memory could be allocated for the allocation of the area. As this case cannot happen anymore, it is also not possible to deadlock in memalign. Therefore the timeout (which would only have prevented the deadlock but wouldn't have solved the edge case anyway) has been removed too. Add options to dump the dedicated grow heap and to only print the current heap count to the "heap" debugger command. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23994 a95241bf-73f2-0310-859d-f6bbb57e9c96
