[issue30919] Shared Array Memory Allocation Regression

[Antoine Pitrou]

Antoine Pitrou added the comment:

Again, setting TMPDIR is a poor workaround as it will impact any library creating temporary files.

I haven't found anyone complaining about limited shared array size on 2.7, so likely it's not a common concern.  Right now, anyone creating a huge shared array on 3.x will be facing huge performance issues, as the array is backed by disk, so it doesn't sound realistic at all to assume people are doing that.
