Steps to Reproduce and Observed Behavior

Taking this code path https://github.com/zigtools/zls/blob/f6580bf87eaf67bd37d776f04d780016f121e647/src/Server.zig#L1056 I've "zig.path" set to "zig" and Build-on-Save enabled.

Loading build configuration notification never ends and zig-childprocesses hang indefinitely.

dir /b \\.\pipe\\zig*

The issue seems to be related to: https://github.com/zigtools/zls/blob/f6580bf87eaf67bd37d776f04d780016f121e647/src/DocumentStore.zig#L1265-L1270

Expected Behavior

I investigated this issue and it appears to be caused by a bug in std.process.Child. See https://github.com/ziglang/zig/issues/24009
