… now reaches openkal-musl 0.11.0, which consumes openkal 0.10.⚠️ ⚠️ TWO OF THE THINGS THIS REPIN CARRIES WERE RECORDED ONE RELEASE AGO AS NOT FIXABLE, and a C++ consumer reaches both through this package and through nothing else. `fcntl(F_SETLK)' took no lock: two programs held one exclusive lock and neither could find out. It excludes now, and the holder is the open FILE --- so a second open file of one name is refused, where the older process-held form would grant it and a library that opened one file twice would destroy its own lock. Anything under a C++ program that locks a file --- a database, a state file, a single-instance guard --- was unprotected and is not now. `kill' upon a program started by `fork' + `execve' reached the copy that waits; the caller was told the program died while it ran to completion. It reaches the program now. And `std::thread::hardware_concurrency()' answered 1 SILENTLY, so a C++ program sizing a pool of workers got one worker and no error. `std::filesystem::space' had nothing beneath it.⚠️ THE VERSION LINE IS THE WHOLE OF WHAT A C++ CONSUMER CAN HAVE, which is what the previous release recorded: a program naming `openkal-musl' itself as well gets neither version. One line.
