# This can draastically improve performance as it allows for the use of `splice()` and `send_file()` syscalls instead of many `read()` and `write()` ones.

# # **WARNING**: Can potentially cause *full system OOM* if the initial size of the input pipe is:
|
|
# * Statically sized (the program can infer the size of standard input.)
|
|
# * The standard input file/buffer pipe size is large enough to pre-allocate enough splicing space to use up the rest of your physical RAM.
