Second, you cannot do a tell on the file handle, because you need to take

My understanding is that calling fflush() before lseek should be fine. See my
upcoming commit.
I'll take a look. But I think you cannot do a relative seek or a tell (which is
a relative seek of 0) without taking into account the buffer.
Here is the issue:
1. you open a file.
2. you read 4 bytes. The FILE object reads 4096 because it wants to fill up its
buffer.
3. you do a tell, expecting 4. If the function does an lseek64 on the file
handle, it gets 4096.
I confirm this is the behavior. I finally found the way to do it on OSX
- import core.sys.posix.stdio and then use fseeko and ftello. See my
latest checkin.
