By default, ActionScript Virtual Machine2 does not impose a limit on how much memory an ActionScript programallocates. On a desktop system, memory allocation failures are infrequent.You see an error thrown when the system is unable to allocate thememory required for an operation. So, on a desktop system, this exceptionis rare unless an allocation request is extremely large; for example,a request for 3 billion bytes is impossible because a 32-bit Microsoft Windows programcan access only 2 GB of address space.
