[revServer] process timeout issue

[Jerry Daniels]

Bob,

We tested revServer engine calls only. No Yoga, Tantra, or Yagya.

Trevor actually found a problem internal to sqlYoga which he fixed, which was causing sqlYoga to attempt to connect twice, which was giving me timeouts of a minute or more.

We think there is some sort of pooling of processes (and possibly users) that are limited by 30 secs. We have seen the timeout in much shorter time spans. Andrew reports a 4 second time out.

Rodeo users are not complaining about their server speeds, Sarah and I are unhappy with the performance because we load test it and see some requests take many seconds to complete and then the next identical request takes less than a second. We can't release a commercial product with this limitation.
