Sure it can, and that's exactly what it means.

Load average measures requests for the processor, not processes
actually getting swapped onto it.

Clearly, a process can never be more than 100% utilized, but your
software might be *asking* for more than it can give, which is why
load averages ever go above 1. (And anything above 1 is too much,
even on mass-used servers. If your load average keeps your processor
at full utilization, that machine is trying to do too much.)

Not totally, but partially.

Sounds like this is a spinning process, based on what Martin just
said.

I suggested rm'ing it out of /proc. (Hey, can't make things any
worse...)
