- I wonder if it is good to use MAP_NORESERVE. From the Linux man page:
|
|
- MAP_NORESERVE
|
|
- Do not reserve swap space for this mapping. When swap space is
|
|
- reserved, one has the guarantee that it is possible to modify the
|
|
- mapping. When swap space is not reserved one might get SIGSEGV
|
|
- upon a write if no physical memory is available.
