kirby@puppetlabs.com 30bf2074fe (POOLER-150) Synchronize checkout operations for API
This commit adds a shared mutex to vmpooler API so that checkout requests can be synchronized across threads. Without this change it is possible in some scenarios for vmpooler to allocate the same SUT to different API requests for a VM.
