Strange that no one has answered this before, it's pretty trivial. Sorry 
for the late reply, I was on vacation.

If an app tries to allocate more than (barrier - held) bytes at once, 
this allocation will fail, failcnt will increase, maxheld won't change.

Say, in your scenario, if 4364184 bytes is currently allocated and a 
program tries to allocate another 2000000 bytes, such allocation will 
fail with no change in held/maxheld and an increment to failcnt.

Hope that helps.

Kir.
