[Haskell-cafe] fcntl locks, executeFile and threaded runtime

[diego souza]

And for the record, the non-threaded runtime never fails (at least
I've never seen once a failure):

$ ghc hs_fcntl.hs
$ sh test_fcntl.sh ./hs_fcntl 2>/dev/null
./hs_fcntl: ok: 1; fail: 0
./hs_fcntl: ok: 2; fail: 0
./hs_fcntl: ok: 3; fail: 0
./hs_fcntl: ok: 4; fail: 0
./hs_fcntl: ok: 5; fail: 0
./hs_fcntl: ok: 6; fail: 0
./hs_fcntl: ok: 7; fail: 0
./hs_fcntl: ok: 8; fail: 0
./hs_fcntl: ok: 9; fail: 0
./hs_fcntl: ok: 10; fail: 0
./hs_fcntl: ok: 11; fail: 0

Thanks!
