Previously, if an error was thrown in a
with_ddoc_proc/2
callback, the process was still returned to the process pool in theafter
clause. However, in some cases, for example when processing a_list
response, the process mightend up stuck in a bad state state, such that it could not be re-used anymore. In such a case, a subsequent user of that
couch_js
process would end up throwing an error and crashing.Fixes #2962
