       Spawn is a small library exposing only one functionality: spawning sub-process.

       It has three main goals:

     

       7
       7
       +
       

     

       8
       8
       +
       1. provide missing features of Unix.create_process such as providing a

     

       9
       9
       +
       working directory

     

       10
       10
       +
       

     

       11
       11
       +
       2. provide better errors when a system call fails in the

     

       12
       12
       +
       sub-process. For instance if a command is not found, you get a proper

     

       13
       13
       +
       [Unix.Unix_error] exception

     

       14
       14
       +
       

     

       15
       15
       +
       3. improve performance by using vfork when available. It is often

     

       16
       16
       +
       claimed that nowadays fork is as fast as vfork, however in practice

     

       17
       17
       +
       fork takes time proportional to the process memory while vfork is

     

       18
       18
       +
       constant time. In application using a lot of memory, vfork can be

     

       19
       19
       +
       thousands of times faster than fork.
