          Issue ID: 23943
           Summary: `execute` causes interrupted system call inside LLDB
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Mac OS X
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: doob at me.com

If I run some code that uses `std.process.execute` inside LLDB it will result
in an exception thrown: "Interrupted system call". It does not occur when
running the program by itself, only when running inside LLDB.

Steps to reproduce:

$ dmd --version

void main()
{
    import std.process;
    execute(["ls"]);
}
$ dmd main.d
$ ./main
$ echo $?

$ lldb main

Most of the times when I run the program the exception is thrown, but not
always. I tried both using DMD and LDC. Both running ARM64 and x86-64 (through
Rosetta).
