nginx-keepalive - Connection count

I have been using the upstream keepalive module and found that the
pool size does not place an upper limit on the number of upstream
connections, but instead simply makes another connection if the pool
size is exceeded. This can be an issue when too many upstream
connections can cause a DoS attack on the upstream resource. 

Could an
option be added to make it wait for a connection to return to the
connection pool - which places an upper limit on upstream connections ?
