-------------------------------+--------------------------------------------
All HAppS (http://happs.org/HAppS/README.html) applications fail with an
 internal error: asyncRead# when compiled with the  -threaded option.

 To reproduce the error:
 - compile any of the apps in the example subdirectory with -threaded and
 access it over the net (http://localhost:8000).

 For example:

 ghc --make -v -fallow-overlapping-instances -fglasgow-exts -threaded
 httpd.hs -o httpd

 The same programs compiled without -threaded work fine.

 Tested on Windows XP with latest SP/patches and gcc 6.4.2.

 Let me know if you would like more info or the full compilation trace.
