I agree with Magnus. Specifically, I suspect there is some sort of
resource contention going on that is driving up the cpu load when the
queries follow certain patterns. This resource contention could be
happening in the win32 port code (likely ipc), the mingw api, or inside
the o/s itself.

Other servers, namely apache, sql server and a host of others do not
have this problem.
