Are you sure about that? I haven't looked into it but while building Chromium with LTO, I get:

../../third_party/gold/gold64: fatal error: out of file descriptors and couldn't close any
clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
[secdev:~/chromium/src/out/Release] (master) s$ ulimit -Sn
10000

Looking in /proc, it has 10013 open file descriptors. With only 2 objects loaded at a time, I'd expect many fewer file descriptors to be open. Maybe it only has 2 objects in memory at once but keeps all the file descriptors open?
