| |
Is any of a userland application's virtual address space reserved? Certainly, some memory is used at startup: the code is loaded into some of the virtual space, as well as the stack. There needs to always be enough space for the stack to grow as necessary. But is any of the space actually marked off as "reserved"? If we just mmap'ed the same file over and over again, could we fill the 4Gb address space with identical mappings, or would we run out?
