Some good news: the new "combreloc" linker feature, which is on by 
default if you use linux binutils 2.12.90.0.1 with a recent glibc, gives 
a measurable improvement in the libgcj startup cost...
before:
$ LD_DEBUG=statistics ./a.out
04296: number of relocations: 47776
04296: number of relocations from cache: 604
after:
$ LD_DEBUG=statistics ./a.out
23496: number of relocations: 16973
23496: number of relocations from cache: 33451
On my PowerBook, the runtime for a "hello world" dropped from ~0.15s to 
~0.11s.
regards
Bryce.
