If the way you refer to file-descriptors is by number, then there is
no way for the garbage collector to prove that a file-descriptor is no
longer in use.

If the garbage collector can't reclaim file-descriptors, then it
becomes the programmer's responsibility to close file-descriptors it
no longer uses.  Exceptions or programmer oversights result in leaked
file-descriptors.
