Instead of forking from the beam process, we create a separate
process in which all forks are done. This has several advantages:
1) performance:
* don't have to close all fd's in the world
* fork only has to copy stuff from a small process
* work is done in a completely seperate process
* a 3x performance increase has been measured,
can be made even greater (10x) if we cache the
environment in child setup
2) stability
* the exec is done in another process than beam, which means that
if the file that we exec to is on an nfs that is not available
right now we will not block a scheduler until the nfs returns.
3) simplicity
* don't have to deal with SIGCHLD in the erts
Unfortunately, this solution also implies some badness.
1) There will always be a seperate process running together with
beam on unix. This could be confusing and undesirable.
2) We have to transfer the entire environment to child_setup
for each command.

Also, some of the branches were testing sizes in bits against a constant
?MAX_BINSIZE, which was in bytes. The signed comparisons masked this
mistake. These branches have been removed since all sizes in bits that
fit in a machine word are valid binary sizes.
Finally, a test that reproduces the issue was added to bs_construct,
along with a test for one of the cases (bs_init<0>(...)) when the test
against ?MAX_BINSIZE must be changed to unsigned rather than removed.

The test whether the result would fit in a smallnum could overflow into
a negative number that would fit a smallnum. A test that reproduces the
issue was added to bs_construct_SUITE.

Can only be caused by distributed messages containing large maps.
Bad map hashing will increase the risk.

This will smoke test the non-copying literals message sending does

that could lead strange things to happen when renaming a node with
a name that already exist in node and dist tables.
Problem:
erts_set_this_node() is a bit brutal and does not handle the case
when an old remote node name is reused as the new local node name.
Solution:
Treat erts_this_node and erts_this_dist_entry as all the others
with correct reference counting.

erlang:is_builtin(erlang, apply, 3) returns 'false'. That seems to be
an oversight in the implementation of erlang:is_builtin/3 rather than
a conscious design decision. Part of apply/3 is implemented in C (as a
special instruction), and part of it in Erlang (only used if apply/3
is used recursively). That makes apply/3 special compared to all other
BIFs.
From the viewpoint of the user, apply/3 is a built-in function,
since it cannot possibly be implemented in pure Erlang.
