better error message for distToNearest

[ssnn]

User reports error with the threshold inference pipeline, setting multiple cores:

Error in unserialize(socklist[[n]]) : error reading from connection
Calls: distToNearest ... recvOneData -> recvOneData.SOCKcluster -> unserialize
Execution halted

With nproc=1, the code can be executed.

I suspect this could be a memory issue. If so, it would be useful to give a more informative error message.

Is the error reproducible? I’ve been using nproc>1 and it runs..
