 Test the realtime GC without linking nimrtl.dll/so.
 
-Note, this is a long running test, default is 35 minutes. To change the
-the run time see RUNTIME in nmain.nim and cmain.c.
+To build by hand and run the test for 35 minutes:
+    $ nim r --threads:on -d:runtimeSecs:2100 tests/realtimeGC/nmain.nim
 
-You can build shared.nim, nmain.nim, and cmain.c by running make (nix systems)
-or make.bat (Windows systems). They both assume GCC and that it's in your
-path. Output: shared.(dll/so), cmain(.exe), nmain(.exe).
-
-To run the test: execute either nmain or cmain in a shell window.
-
-To build by hand:
-
-  - build the shared object (shared.nim):
-
-    $ nim c tests/realtimeGC/shared.nim
-
-  - build the client executables:

+xxx do we still need tests/realtimeGC/cmain.c?
