   That's correct.

   In most cases that works fine. If you want to be safe, you have to either   
   a) set the global system unit variable ReturnNilIfGrowHeapFails to true,   
   and getmem will return nil when no more memory is available   
   b) use exceptions to catch the run time errors (which are converted to   
   exceptions if you use the sysutils unit) which occur when an   
   out-of-memory condition occurs.
