I thought I'd add this bit of information. After stopping
a number of simulations by pressing 'Ctrl-Z' in the middle
of the sim, I will get the following buffer error:
gr::vmcircbuf_sysv_shm: shmget (2): No space left on device
gr::vmcircbuf_sysv_shm: shmget (2): No space left on device

what(): std::bad_alloc

I found a post that Martin Muller made explaining how to
overcome this (execute: sudo sysctl kernel.shmmni=32000), but
I'm more interested in whether this could be related to the
stalling I'm seeing.
