encoding/gob: test suite now apparently requires >8GB of RAM #28321
Description
Since CL 143678 (encoding/gob: increase "tooBig" from 1GB to 8GB on 64-bit machines), I'm no longer able to run the encoding/gob test suite on my machine (with 8GB of RAM). Running the tests kills my OS.
The longtest builder is also failing, presumably for the same reason:

The tests should probably be tuned so that they don't require >8GB of RAM to be run.
