Eclipse–“run to line” in debug mode

Using Eclipse 3.2.1, Olimex LPC-P2103 board w/ JTAG wiggler, GCC 4.0.2, OCDRemote. Everything ran OK until we got multiple tasks (2 right now) being scheduled. Once I start the scheduler the "run to line" feature in Eclipse’s debug view no longer works. I assume this is related to how in standalone GDB you need to suspend other threads to get reliable stepping. Anyone out there who can explain how this is suppsoed to work, please bail me out there. P.S. let me know what else you need ot know about our environment if I haven’t provided enough info.
