tree-kill: spawns too many pgrep processes, causing the extension to become unresponsive #90

This exactly the same bug as microsoft/vscode-go/issues/3191, only difference few saves will trigger it, while in the previous case it was enough few slow saves. This behavior drives me crazy, and guys... I really don't want to use gogland. |

Hm, looks like you are encountering an issue with the If I recall correctly, on the original issue, @hyangah mentioned that @butuzov: Is it possible you're encountering something like pkrumins/node-tree-kill#17 (comment)? |

Looks like you're encountering pkrumins/node-tree-kill#17. Seems like a simple workaround would be to at least wrap the tree-kill usage in a try-catch. Edit: The try-catch will not actually fix the issue, but it will at least catch the TypeError. To fix the underlying issue, we will either need to figure out the issue in tree-kill and contribute a fix, or fork and maintain tree-kill ourselves. |

@stamblerre great finding. I looked into the tree-kill code and definitely there is a race condition. But not only that, I also observed the default
I can't say all the pgrep issues users were reporting were due to this, but definitely, this can be one of them. @butuzov are you using |

Use the default pgrep, available since os x mountain lion. proctools' pgrep does not implement `-P` correctly, returns unrelated processes, breaks tree-kill's assumption, and may cause a large number of pgrep processes. Reported in pkrumins#17 (comment) Update golang/vscode-go#90 (comment)
