I gave it a shot, and it got as far as compiling loop.c:

loop.c: In function ‘Coolio_Loop_run_nonblock’:
loop.c:277: error: ‘TRAP_BEG’ undeclared (first use in this function)
loop.c:277: error: (Each undeclared identifier is reported only once
loop.c:277: error: for each function it appears in.)
loop.c:279: error: ‘TRAP_END’ undeclared (first use in this function)
make: *** [loop.o] Error 1

I don't know what TRAP_BEG and TRAP_END do in MRI, but those would be
the next ones to implement in JRuby's cext support...
