That's it for the basic response definition. Now we can start mucking with the
responses to break clients. One common hard-to-test circumstance is hangs or
slow responses. Pathod has a pause operator that you can use to define
slow responses. _pathod_ has a pause operator that you can use to define
precisely when and how long the server should hang. Here, for instance, we hang
for 120 seconds after sending 50 bytes (counted from the first byte of the HTTP
response):
