[PATCH v3] configurable maximum number of clients

[Olivier Fourdan]

Hi all,

Could someone be so kind and take some time to do a review of this patch?

I know it's quite intrusive but tbh such a feature requires to touch the core of the X server.

It seems to work fine here (see my other email [1] with the test programs used to verify).

Thanks in advance,
Olivier
