Why is the main thread bound?
I can answer myself: if the main thread is unbound, the end of the
program can be reached in a different OS thread, which may be a
problem if we want to return cleanly to the calling code.
I've now implemented a

Linux/NPTL.

For some reason, these two functions have different types.
fun1 f (Left x)= Left (f x)
fun1 _ r@(Right x) = Right x
fun2 f (Left x) = Left (f x)
fun2 _ r = r
Is there a way to rewrite fun2 so that f has type (a-b)?
In the general case, it seems wasteful to have to destruct and
construct
Hi,
If I have a C function returning a structure (not a pointer, but
structure itself), can this be accomodated via FFI?
I re-read the FFI Addendum, and my conclusion is most likely No. I am
asking just to make sure this is not only my finding.

No. The way data is organised in memory is dramatically different in
Haskell when compared with C. You need to write functions to read in
each field
