[boost] [Interprocess] Managed mapped file questions

Hi First of all, thank you for boost interprocess :-) I have a couple of questions: 1. When you grow a managed mapped file, the current implementation fills all the new space with zeroes. This is less efficient than just resizing the file. The comments in the code implies there is a reason, so what is it? 2. When the size to map is too small, take 1 or 2 bytes for instance, the library fails in a non elegant way. This is a corner case, but I could not find this documented. Is this a bug? I'm asking this before sending any sample code or creating tickets, but of course I could do that as well if there is the need. Thanks again. Cheers Jorge
