Does anyone remember the reason that processes blocked

I'm asking because I'm banging on FreeBSD and I can wedge it hard, to
the point that it won't recover, by just beating on tons of memory.
My understanding was that signal delivery only happens when the process is
*running* in the kernel. If the process is sleeping on IO then it's not
running, so the signal isn't delivered.
