Well, yes, but I believe that is not this quota privilege.

For example, from
http://www.microsoft.com/technet/security/topics/issues/w2kccscg/w2kscgcc.mspx
and repeated in
http://www.microsoft.com/technet/security/prodtech/win2000/win2khg/appxb.mspx
http://www.microsoft.com/Resources/Documentation/windowsserv/2003/all/techref/en-us/ntrights_remarks.asp
etc
Increase quotas (SeIncreaseQuotaPrivilege)

Allows a process that has Write Property access to another process to
increase the processor quota that is assigned to the other process. This
privilege is useful for system tuning, but it can be abused, as in a denial
of service attack.

AIUI this allows an account to change the process's quanta, which is used
by the scheduler algorithm when it comes time for the adjusted process to
get a time-slice so that the process gets a larger/smaller than normal
slice.
