Split your bigfile size across N machines.
Have a process on each machine that processes a filesize/N chunk of the bigfile. (Say, 32 machines each reading a different 32GB chunk of your 1TB file.)
Each reader accumulates word counts in a hash until the hash size approaches it's memory limit.
(Assume ~1.5GB/10 million words/keys on a 64-bit Perl; somewhat less on a 32-bit.)
When that limit is reached; it posts (probably udp) out the word/count pairs to the appropriate accumulator machines; frees the hash and continues reading the file from where it left off.
No threading, shared memory or locking required. Simple to set up and efficient to process.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
