+ .description("If this option is set to 'true', when a NUL
character is read, the processor will yield and try to read the same part again
later. "
+ + "The purpose of this flag is to allow users to handle cases
where reading a file may return temporary NUL values. "
+ + "NFS for example may send file contents out of order. In
this case the missing parts are temporarily replaced by NUL values. "
+ + "CAUTION! If the file contains legitimate NUL values,
setting this flag causes this processor to get stuck indefinitely. "
Review comment:
I intentionally used "this" to emphasize a bit more that what is going
to be stuck is the current processor.
