// Implements dylib loading and searching by making calls to

// ExecutorProcessControl::callWrapper.
|
|
//
|
|
// This simplifies the implementaton of new ExecutorProcessControl instances,
|
|
// as this implementation will always work (at the cost of some performance
|
|
// overhead for the calls).
