Increasing maximum number of concurrent processes directly increases memory usage?

[Jeremy Raymond]

Hello,

If I startup erlang with no arguments (just run erl) it's memory usage as
reported by top starts off at around 10 000 bytes. If I start it and
increase the maximum number of threads (erl +P 134217727) the memory usage
out of the gate is 1.0 gigabytes. Why is this the case?
