The static linking workarounds are for a Cray MTA/2, a multithreaded 
supercomputer.   Although having a rather primitive runtime environment 
(e.g. no dynamic linker), it does have an advanced parallelizing 
compiler.   (The practical usage is kind of fly-by-wire setup using a 
front-end workstation.)  The MTA/2 is fast architecture for 
memory-intensive applications.
