Brief time out of observe to restart CW hardware injection code

Camilla, Dave:

WP11290. To free up memory on h1hwinj1 we restarted the psinject process on h1hwinj1. This in turn took H1 out of observe due to gain ramping of the INJ_CW filter module.

Before the restart h1hwinj1 had 2GB memory free, which would have lasted only until 4am PDT tomorrow (Friday). After the restart it now has 14GB available, which should take us through to late Sunday. A second restart will be needed over the weekend, and the memory leak will be fixed next Tuesday.
