On posix platforms besides OSX, std.process.browse uses a fork/exec to open a browser window. When this fails, it's the exec that fails. However, the function returns instead of exits. This means it keeps executing whatever it was doing in the parent process when `browse` was called! And with only one thread, with everything else in the process still allocated/opened. This is disastrous. The process should exit right away. Technically this should be redone to use std.process utilities directly, but I just want to make sure this bug is fixed, so I'm making a separate bug. I'll open a separate issue on the enhancement to replace browse internals with std.process regular functions. That originally was captured in issue 6496, but that was closed incorrectly.
@schveiguy updated dlang/phobos pull request #9065 "Fix issue 24824 - ensure we exit a child that does not succeed in exec." fixing this issue: - Fix Bugzilla Issue 24824 - ensure we exit a child that does not succeed in exec. https://github.com/dlang/phobos/pull/9065
Note, I guess OSX is included here, but `open` always exists, so you wouldn't ever see this issue.
