A race condition would be like, if they were trying to both write to the same file on disk simultaneously. Process 1 writes "hello", process 2 writes "world", you could get "helloworld", "worldhello", or maybe even "worhello"...
If they're just doing their own thing and not bothering each other they'll get along fine.

I have written a some six scripts to move large files and re-size them. This has been done step by step, taking backup, creating the new files, merging the files, removing the temporary files created.
Since these files are around 500 MB, each step takes somewhere between 1 to 5 mins.

whocalls
whocalls(1) User Commands whocalls(1)
NAME
whocalls - report on the calls to a specific procedure
SYNOPSIS
whocalls [-l wholib] [-s] funcname executable
[arguments]...
DESCRIPTION
whocalls is a simple example of a utility based on the Link-Auditing functionality of ld.so.1(1) that permits the tracking of a given func-
tion call. See the Linker and Libraries Guide for a detailed description of the Link-Auditing mechanism. The executable is run as normal
with any associated arguments. Each time the procedure funcname is called, both the arguments to that procedure and a stack trace are dis-
played on standard output.
OPTIONS
The following options are supported:
-l wholib Specifies an alternate who.so Link-Auditing library to use.
-s When available, examines and uses the .symtab symbol table for local symbols. This is a little more expensive than using the
.dynsym symbol table, but can produce more detailed stack trace information.
EXAMPLES
Example 1 Tracking Function Calls
The following example tracks the calls to printf() made by a simple helloworld program:
example% whocalls printf helloworld
printf(0x106e4, 0xef625310, 0xef621ba8)
helloworld:main+0x10
helloworld:_start+0x5c
Hello World
