If I understand this correctly, there's a difference between deleting a reference to 50 GB (like an inode), and actually writing 50 GB.
When you write to an output port, you are writing to a buffer in memory. This prevents the slow downs you've witnessed, because storage mediums are comparably slow. "Flushing" with (flush-output) or plumbers on port closure actually sends bytes outside of the process. I wouldn't try using the same port after deleting a file. If Racket and the operating system initially agreed on a file descriptor that is now invalid, then you'll need to address that by opening a new port. Note that I don't Racket's implementation details here. I'm recalling what I've seen happen across languages. On 12/19/21 11:50 AM, Jacob Jozef wrote: > Hi > > I start a thread printing a file.
