pnpm: pnpm won't worked with node-newrelic.

pnpm version:

pnpm 0.39.0 (but I think all versions of pnpm.)

Code to reproduce the issue:

• Install packages with pnpm ($ pnpm install)
• Launch node app with node-newrelic.

Expected behavior:

• Successfully launched within seconds.

Actual behavior:

• node-newrelic try to walk-through all node_module packages
  • But fell down to the symbolic hell (which well-gardened by pnpm), and It won’t return.

Bypass way:

• Launch with NEW_RELIC_ENABLED=false

Additional information:
