Deleted files only disappear from the directory listings. File space is
not freed until the last process closes the open file.
A programming "trick" is to create/open temporary file(s) when program
is launched then unlink (delete) the file(s) while they are still open.
As long as one has an open file handle the files are perfectly usable.
When program terminates normally or by exception, the OS cleans up and
no mess is left.

There is an 8% reserve that only root can eat into. You are 3 MB into
your 8% reserve. This is BSD Unix 101.

A reboot is the fastest way to close open files and release their space.
