The following files were removed from the main branch since they very likely won't be used anymore: SftpJobModule/BBSftpPollerRejection.qc SftpJobModule/BaseSftpPollingJob.qc SftpJobModule/BaseSftpPollingRejectionJob.qc tests/SftpModule/BBSftpPollerRejection.unit.qtest tests/SftpModule/sftp-polling-job-example-v1.0.qjob tests/SftpModule/sftp-polling-rejection-job-example-v1.0.qjob

The reason is that they do not provide atomicity as we need it and want to ship to customers.
