I don't what he meant by a broken libc, if it is the fact that there
is a lot of deprecated standard functions, I don't call it broken

new safe functions, although it does not deprecate these functions).

Hi!
I was in fact experimenting with this. The solution seemed to lie in
simple memmap as it is implemented in Windows:
import numpy as N
def arrSharedMemory(shape, dtype, tag=PriithonSharedMemory):
Windows only !
share memory between different processes if same `tag` is used.

Maybe that's why it crashed ;-) !? But for simple use it seems
fine.
I just did some code (below) that does read/write to the array AFAP,

Is anyone sharing arrays between processes on Windows?
I tried compiling the posh sources (once, so far) with the new MS

What other solutions are in use?
Have a second process create an array view from an address would
suffice for this particular purpose. I could pass the
