Detailed Description

Holds file descriptors for host-backed files; host-backed files are files which were opened on the physical machine where the simulation is running (probably the thing on/under your desk).

All regular files are redirected to make it appear that the file descriptor assignment starts at file descriptor '3' (not including stdin, stdout, stderr) and then grows upward.
