When it is specified, the nimsuggest instance monitors whether this process is still alive. In case it's found to be dead, nimsuggest shuts itself down. Currently only implemented on POSIX and Windows platforms. The switch is silently ignored on other platforms. Note that the Nim language server should still try to shut down its child nimsuggest processes. This switch just adds extra protection against crashing Nim language server and gets rid of the remaining nimsuggest processes, which consume memory and system resources.
