This option should refer to the full path to a binary or script that can preprocess configuration files prior to them being parsed by the datasource libraries.
Depending upon your choice of preprocessor, this allows variables to be substituted, extended logical conditions to be validated and generally reducing the configuration management requirements.
The preprocessor should take as its first argument the name of the file to process, and output a rewritten configuration file to standard out.
This feature has been extensively tested using the GNU M4 macro processor.

Release 4.4 of the Caplin Platform introduced a major new feature and an important pre-requisite for components that sit within the platform.
Prior to 4.4, all DataSource messages were serviced on a single thread and callbacks could be guaranteed to occur only on a single thread. With 4.4, multiple threads service DataSource messages, with the result that callbacks can occur on more than one thread and that more than one callback may be in progress at any point in time.
In order to maintain source compatibility with products built using older versions of DSDK, all callbacks into the application will occur on the thread that called ds_loop(), this naturally introduces a synchronisation point and will impact performance.
Enabling this option will remove the synchronisation point and performance will be increased, however the application must be threadsafe.
