Thanks Carsten, I've compiled your example and all works as expected.
Just a note.
If I load the module in GHCi (intead of compiling it) and launch main
function the result is quite strange. I obtain:

So we actually observe the concurrency here,
Hi Luca,
Just in case you weren't aware of it, your example didn't actually
contain any STM (beyond the import), just regular Haskell IO-based
concurrency.
But the answer to your question is that there's no synchronization on
writing to a file descriptor, so both threads are simultaneously
Thanks Dan.
I understand, your explanation is clear.
I just need to study more Haskell. Im' just a beginner but very
