[Xymon] LDAP Check causes xymonnet to hand

[Thomas Vachon]

We are having issues with xymonnet handing on 4.3.12 (happened on 4.3.10
too).  As soon as we added an ldap check which can hang (due to the ldap
server being in a bad state), xymonnet hangs and goes purple on all remote
checks.

Nothing shows in the logs. Here is the historical xymonnet info from the
last purple:
