Apex has built-in a distributed compilation facility.  However, it does
not work well with Ada.  (It was intended for C++).

If you select a bunch of source files and try to "code in parallel" they
all run one at a time on one machine.

If you select several _views_ and code in parallel, each view is a
separate job on the next available machine from your "execution list" (a
file in a particular format in a particular place).

But suppose you have package X in one view and package Y in another. 
Both with package Z.  If Z has been changed, then when one job gets to
package X, it will first update Z.  If another job gets to package Y at
the same time, it will also try to update Z.  Both jobs will be writing
into the DIANA nets which will be corrupted.
