Gather latency measurements of common operations to determine overhead of Pyronia:

• [ ] latency of file read with varying callstack depth
• [ ] latency of file read with varying numbers of threads
• [ ] latency of network connect with varying callstack depth
• [ ] latency of network connect with varying numbers of threads
• [ ] memory overhead of native library isolation
• [ ] sub-process exec lead time
• [ ] absolute memory overhead of Pyronia (i.e. size of metadata in userspace and kernel)
