Description

I'm not sure there's anything we can do about this other than to make a private copy of blobxfer which plays more nicely with writable keep mounts, so this is primarily a reminder to document the current behavior. The file space preallocation code fragment below fails with an "I/O error" on the file close. The full output is below that.

        if allocatesize > 0:
            filedesc.seek(allocatesize - 1)
            filedesc.write(b'\0')
        filedesc.close()
