Comment(by yurij):

 _endthread calls CloseHandle, so it should be the right API.


 In fact, I`m trying to workaround FFI bug with hs_init/hs_exit:
 http://www.haskell.org/ghc/docs/7.2.1/html/users_guide/bugs-and-
 infelicities.html#ffi-divergence

 I`ve found some global/thread-local variables (myTask, allocs,
 generations, mblock_allocated) which doesn`t properly set to NULL/0 on
 hs_exit and set it to NULL in appropriate finalization functions but
 obviously it is not enough to fix segfaults after repeated runtime
 initialization/deinitialization.

 So I try to use LoadLibrary/hs_init/use haskell
 functions/hs_exit/FreeLibrary call sequence to avoid this problem and
 notice this handle leak.
