add shared mapped file (in progress)
...
implemented:
- Pages can be shared between maps.
- A change made to a map is written to the file, at munmap().
not yet implemented:
- VM operation during page IO execution.
Because page IO is executed with VM's lock.
- Page IO, which does not change a file size with any case.
When munmap() races with truncate(), the file size may be changed
illegally.

refuse the write to a read-only memory

It was able to change a read-only memory using a system call that
forwarded to host.

prevents MCKERNEL_RLIMIT_STACK from overwriting
...
When mcexec reduces a stack, mcexec stores the original RLIMIT_STACK
in environment variable MCKERNEL_RLIMIT_STACK.
A fix to prohibit overwrite of this time.
Therefore, the value of RLIMIT_STACK of the McKernel's process is
decided in the following order.
(1) If environment variable MCKERNEL_RLIMIT_STACK exists; the value.
(2) A value of RLIMIT_STACK in the mcexec starting.

mcexec: add a upper limit of the stack size

- When the stack size is greater than 1 GiB, reduced to 10 MiB.
- To achieve a reduction of the stack, restart itself using the exec().
- By using the environment variable MCKERNEL_RLIMIT_STACK,
tell to McKernel the stack size of the original.
