// (a DOOM bug).

// Process each thinker. For thinkers which are marked deleted, we must
// load the "next" pointer prior to freeing the node. In DOOM, the "next"
// pointer was loaded AFTER the thinker was freed, which could have caused
// crashes.
//
// But if we are not deleting the thinker, we should reload the "next"
// pointer after calling the function, in case additional thinkers are
// added at the end of the list.

// external and using P_RemoveThinkerDelayed() implicitly.
