Bug report

https://github.com/phpstan/phpstan-src/blob/master/src/Parallel/ParallelAnalyser.php#L146

This is forcibly terminating the process while it may still be working during the loop. This causes some errors detected by child processes to not be reported.

I don't know exactly how to reproduce this problem, but it happens 90% of the time on an aarch64 mobile device with 8 cores (don't judge pls).

SIGTERM exit codes are reported to the react process exit hook - signals which were sent by PHPStan itself.

The most obvious solution seems to be to not forcibly terminate the process, but just close STDIN, so that the child process loop will break, but still report back the final errors that it found.

Removing this call seems to make my problem go away locally: https://github.com/phpstan/phpstan-src/blob/master/src/Parallel/Process.php#L130
However I don't know if this may have side effects, or even if it fully works.

Code snippet that reproduces the problem

I don't have a reproducing sample because it happens in a large project and I can't seem to pin it down; besides, it seems to be platform dependent.
