RFC: Scheduler behaviour

Hello,
in these days I was analyzing the Nagios scheduler activity and I've
noticed a strange schema of execution about plugins/checks.
I've about 1000 checks to do in a short time so I've set the concurrent
check parameter to 90 checks per time.
Looking at the processes activity on the server I've noticed that the 90
processes are normally forked, then, one after the other they are
completed regularly.
A Nagios process for each forked plugin remains still... it seems
waiting for the other processes to finish.
All flows perfectly until there are some hosts in down state that need
the use of check-host-alive by Nagios.
What happens is that all the "still" Nagios processes waiting for the
last one to exit remain "still" until the check-host-alive command
completed.
Acting this way the next 90 checks are not fired immediately by Nagios
but only after the last check-host-alive command completes, thus,
wasting a lot of time and incrementing the total time of execution for
all the checks (actually 1000 checks performed in about 20 minutes).
To workaround this I've replaced ping with fping that is faster (on
check-host-alive), reduced fping retries to 3 instead of 5 and reduced
the timeout values in nagios.cfg. Now Nagios is faster but it still
waits for the slowness of check-host-alive.
Maybe that I'm wrong, in fact I've NOT browsed into the scheduler
sources of Nagios but it seems that the scheduler isn't written to
maximize CPU utilization.
What I've noticed is that:
1) Nagios forks 90 processes
2) Waits for 90 subprocesses (plugins) to finish
3) Collects and stores all results
4) Prepares the next 90 processes and then GOTO 1
Why Nagios waits all 90 processes before forking again other checks? If
80 checks have been already done and 10 are slow (ie. check-host-alive)
why have I to wait to fork 80 checks more? I mean, the scheduler is it
intended to work this way or is a yet to come feature to have always 90
concurrent active checks, treating them indipendently?
The following screen captures will show the situation in real time to
better explain what I've described.
The scheduler forks the checks:

After few seconds the check-host-alive causes Nagios to wait on all
forks instead of firing other checks:
