I have a 112-core Intel CPU, and each time a sccache is invoked, it makes 112 clone syscall; and when I try to parallel build with -j112, there are 112*112=12544 clones in total, which may cause EAGAIN error (especially in a container environment).

Reproducer:

$ nproc
112
$ sccache --start-server
sccache: Starting the server...
sccache: Listenning on address ...
$ strace -e clone sccache gcc -c a.c |& wc -l
114

Version:

$ sccache --version
sccache 0.12.0
