Handle converted from Fd with fdToHandle contains nothing

[AleXoundOS]

Is fdToHandle supposed to work with the file descriptor, returned by memFdCreate?

I can be wrong but it seems that the returned Fd is not the proper Fd haskell knows of. Perhaps it should be created with mkFd?

Also, despite fdWrite works, fdRead not - throws EOF exception:

fd <- memFdCreate "test" []
fdWrite fd "Test text"
fdRead fd 1
*** Exception: fdRead: end of file (EOF)

Sorry for my poor knowledge of file descriptors. Solution is to run this before reading from the beginning:

fdSeek fd AbsoluteSeek 0

Both fdRead and fdToHandle work then.
