No, the space on the file is not yet marked as free. *However* for
ext3 and ext4, the inode has been placed on the orphaned inode list,
so that if the system crashes, part of the journal recovery process
will at that point free the blocks.

Not currently using ext3/ext4, no. There would have to be an entirely
new system call or other userspace interface for something like this.
