awake-time long lags

Hi there,

we are encountering another weird problem: a (very) long lag awake-time.

We happen to log the application-level awake and some of the component-level
awakes. Normally, the latter happen just a couple milliseconds from the former.
Nevertheless _sometimes_ when the load gets higher and more R/R loops run
concurrently, this lag grows up to a complete nonsense — tens or, in the worst
cases, hundreds of seconds (between Application.awake and some Component.awake).

The most obvious answer that either the session-level awake or some of the
non-logged component-level awakes might take an eternity upon a higher load is
still an open possibility, but quite improbable one: we have profiled our
application when the problem did happen with a smaller load, a couple of times
the lag grew up to about 5-7 s, and still none of the awake methods ever took
more than 40 ms.

Has perhaps anyone here encountered a similar problem and might suggest a
solution or at least a reasonable way to find the culprit?

Thanks and all the best,
OC
