Description

When you run LDV tools in parallel mode (for example, with LDV_MAX_RCVS=2 setting), LDV spawns watcher processes when it should queue a task and proceedes. (In the non-parallel mode it waits for them to finish after spawning) As a result, when you check a lot of drivers (for example, when you check the whole kernel) the system gets polluted with a lot of not-so-small (8-10 Mb each!) processes that just wait for a semaphore, making the usual kernel check mode implausible.

This should be fixed.
