Konstantin Belousov e474e51e07 Eliminate the static buffer used to read the first page of the mapped ... object, and eliminate the pread(2) call as well [1]. Mmap the first page of the object temporaly, and unmap it on error or last use. Potentially, this leaves one-page gap between succeeding dlopen(3), but there are other mmap(2) consumers as well. Fix several cases were the whole mapping of the object leaked on error. Use MAP_PREFAULT_READ for mmap(2) calls which map real object pages [2].
