Thanks for your kind help!
OK, I now have a binary dynamically linked against /lib/libc.so.6, (according to ldd), and that points to glibc-2.1.92. And I tried setting the environment variables you suggested, I checked that they are set and checked that they appear in /lib/libc.so.6. But the behaviour is unchanged: MAGMA still hits this barrier at 830M (not 870M, that was a typo).
I guess I conclude that either (1) MAGMA does not use libc's malloc (checking on this, I doubt it) or (2) glibc-2.1.92 knows of these variables but has not yet implemented the tuning (I'll try glibc-2.2) or (3) this is not the problem.
I'll look at Andrea's hack as well. Thanks for everybody's help!
Cheers, Wayne
