Max number of open file descriptors is too low

It seems that on Windows max_files in erts/emulator/sys/win32/sys.c
is just preset at 1024.
I see the following at the top of the file:
static int max_files = 1024;
I see sys_max_files() that returns the value of max_files and I see
max_files being used all over the place. I do not see any functions
that could be used by Erlang to set max_files to the value of
It looks like a bug to me. If the intention was to set max_files to
ERL_MAX_PORTS then there's no code in the emulator bootstrapping
functions to do so.
