A method includes executing one or more applications in an execution environment. The one or more applications are capable of requesting allocation of memory during execution. The method also includes allocating a plurality of memory blocks in a heap to the one or more executing applications. The plurality of memory blocks are allocated sequentially in the heap to the one or more executing applications. In addition, the method includes deallocating the plurality of memory blocks during a single deallocation. Memory blocks in multiple heaps could be allocated to the one or more executing applications. A particular memory block in a particular heap could be allocated to a particular executing application by pushing an indicator identifying the particular heap onto a stack. The particular memory block is allocated in the particular heap based on the indicator, and the indicator is popped from the stack after allocation.
