[ale] Low entropy on vm

User was trying to transfer data to/from oracle on Linux. The connection
kept dropping. The Linux system is a vm on ESXi. The physical host is a tad
overloaded on memory not complaining about cpu cycles.

By telling oracle to use /dev/urandom instead of /dev/random, the
connection drops went away.

Could the vm be not getting enough cpu cycles to keep entropy pool full or
should I look somewhere else? Ideas to boost entropy collection rate are
appreciated.
