http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libc/port/rt/sched.c#374 (choice of limited vs open-end time quantum) ...and then the RT class implements the settings passed to it via priocntl(2); so you won't see mention of POSIX scheduling classes in the kernel code. I think it enforces the time quantum at http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/disp/rt.c#984 (I _think_ I got that right...)
