+   • Over time, the backing file will be filled with memory “leaked” by
+     ‘gawk’ as it runs.  Most notably this is the memory used to compile
+     your program into an internal form before running it, which happens
+     each time, but there are other leakages as well.  (For an extreme
+     example of this, see this thread

+     in the <bug-gawk@gnu-org> mailing list archives.)  It is up to you

+     is, and arrange to dump any data you may need before the backing
+     file becomes full.
