 // An NmethodSweeper is an incremental cleaner for:
 //    - cleanup inline caches
-//    - reclamation of unreferences zombie nmethods
-//
+//    - reclamation of nmethods
+// Removing nmethods from the code cache includes two operations
+//  1) mark active nmethods
+//     Is done in 'mark_active_nmethods()'. This function is called at a
+//     safepoint and marks all nmethods that are active on a thread's stack.
+//  2) sweep nmethods
+//     Is done in sweep_code_cache(). This function is the only place in the
+//     sweeper where memory is reclaimed. Note that sweep_code_cache() is not
+//     called at a safepoint. However, sweep_code_cache() stops executing if
+//     another thread requests a safepoint. Consequently, 'mark_active_nmethods()'
+//     and sweep_code_cache() cannot execute at the same time.
+//     To reclaim memory, nmethods are first marked as 'not-entrant'. Methods can
+//     be made not-entrant by (i) the sweeper, (ii) deoptimization, (iii) dependency
+//     invalidation, and (iv) being replaced be a different method version (tiered
+//     compilation). Not-entrant nmethod cannot be called by Java threads, but they
+//     can still be active on the stack. To ensure that active nmethod are not reclaimed,
+//     we have to wait until the next marking phase has completed. If a not-entrant
+//     nmethod was NOT marked as active, it can be converted to 'zombie' state. To safely
+//     remove the nmethod, all inline caches (IC) that point to the the nmethod must be
+//     cleared. After that, the nmethod can be evicted from the code cache. Each nmethod's
+//     state change happens during separate sweeps. It may take at least 3 sweeps before an
+//     nmethod's space is freed. Sweeping is currently done by compiler threads between
+//     compilations or at least each 5 sec (NmethodSweepCheckInterval) when the code cache
+//     is full.
