leak

   With qualifier, one of a class of resource-management bugs that occur
   when  resources  are  not freed properly after operations on them are
   finished,  so  they  effectively  disappear (leak out). This leads to
   eventual exhaustion as new allocation requests come in. {memory leak}
   has  its  own  entry;  one might also refer, to, say, a window handle
   leak in a window system.
