Greg's suggestion of bumping the values for shmmni and shmseg helped to solve 
the shmat(1) related matter. shmget(1) still fails with "invalid argument" 
when the second parameter of shmget evaluates to 8396800 - e.g.

shmget(IPC_PRIVATE=0, size=8396800, pagesize=4096)

No luck with thread related errors. It may be due to recent changes we had in 
the NetBSD source tree.

Running the usual suspects from gnuradio-examples appear to be fine.
