Hello,
GDAL 3.6 added support for multi-threaded reading using PRead, but I couldn't
spot ReadBlock using the same code path. On the other hand, I didn't see it
taking a lock either, so I'm a little confused :-). My question is whether
ReadBlock supports concurrent reads or not (*).
(*) I think these can also be implemented at VSI level by wrapping a file
handle and turning Seek + Read into a PRead (when supported), even for drivers
that don't explicitly support PRead.
Thanks,
Laurentiu
