The LDM (actually, the product-queue library) is specifically designed
to handle concurrent access -- so your situation won't be a problem.

Remember to run the pqinsert(1)s out of the LDM configuration-file via
the EXEC action so that the SIGCONTs generated by the pqinsert(1)
processes upon insertion of a data-product are sent to to other
processes of the LDM system.
