log import needs ability to write mark records?

[Mark Goodwin <mgoodwin@xxxxxxxxxx>]

collectl2pcp can take multiple input logs from collectl and create a
single PCP archive. The input logs are often not temporally contiguous,
i.e. there may be a time interval between one log and the next.

Replaying the PCP log produces some unexpected results, and I suspect this
may be due to missing mark records. Is there any way to write out a <mark>
record in the PCP log, between processing input files? I don't see any
pmiFoo API function in LOGIMPORT for this ...?

maybe it's better to write individual PCP logs, and then merge them?

Thanks
