[Bug-Candidate]: Maximize CPU output when running fuzzer

[0xicingdeath]

Describe the issue:

When deployed on a 16 core machine, with 15 workers, the CPU usage seems to be maxed at about 40-50%. When deployed on an 8 core machine, with 7 workers, CPU usage has only ever hit a max of around 65%.

Code example to reproduce the issue:

Follow instructions for reproduction here, and if testing on cloudexec, then run make ec (for echidna-cloud) or make el (echidna-local).

Version:

Relevant log output:

No response

Can you check if this a regression from a previous version? I think @elopez reproduced this with the current version as well.

This applies to previous builds as well – or at least the branches for fixes on Curvance between 2.2.2 and 2.2.3.
