From: Johannes Schindelin <johannes.schindelin@xxxxxx> In Git for Windows, we use the MSYS2 Bash which inherits a non-standard PID model from Cygwin's POSIX emulation layer: every MSYS2 process has a regular Windows PID, and in addition it has an MSYS2 PID (which corresponds to a shadow process that emulates Unix-style signal handling). With the upgrade to the MSYS2 runtime v3.x, this shadow process cannot be accessed via `OpenProcess()` any longer, and therefore t6500 thought incorrectly that the process referenced in `gc.pid` (which is not actually a real `gc` process in this context, but the current shell) no longer exists. Let's fix this by making sure that the Windows PID is written into `gc.pid` in this test script soo that `git.exe` is able to understand that that process does indeed still exist.
