Summary: Sometimes, EdenFS goes bonkers and talks to 'hg debugedenimporthelper' a lot for seemingly no reason. Make these situations easier to debug by counting how many requests EdenFS makes to 'hg debugedenimporthelper'. These counters let us answer questions such as the following: * When performance sucks, is EdenFS is making a lot of requests or only a few requests? I.e. is Hg slow at responding or is EdenFS very demanding? * Does a recent performance issue correlate with EdenFS communicating with 'hg debugedenimporthelper'? * Which engineers are outliers having orders of magnitude more 'hg debugedenimporthelper' requests than p50 engineers? We could get fancier with these counters and include the number of bytes received, the duration of the request, etc. For now, just having a request count is useful.
