Re: [ros-dev] Window Handle Leak

[James Tabor]

Hi all,
Good read for those of us that forget how this works,

http://msdn2.microsoft.com/en-us/library/ms725486.aspx

User interface objects support only one handle per object. Processes
cannot inherit or duplicate handles to user objects. Processes in
one session cannot reference a user handle in another session.

There is a theoretical limit of 65,536 user handles per session.
However, the maximum number of user handles that can be opened per
session is usually lower, since it is affected by available memory.
There is also a default per-process limit of user handles. To change
this limit, set the following registry value:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Windows\USERProcessHandleQuota

This value can be set to a number between 200 and 18,000

Found two bugs and the one pointed out by Stefan100 on IRC.

Thanks,
James
