Apologies for the slow response.

I ran each program with an argument of 500 for good measure.  All four 
programs successfully create and then delete a large number (presumably 
500, I didn't count 'em!) of apreq* temp files.

apr_temp and apr_temp_sh both deleted all those files about as quickly 
as they were made (i.e. very quickly), while apr_temp_nc and 
apr_temp_nc_sh both output loads of CLEANUP messages in the console 
quickly but then seemed to hang for nearly a minute, during which time 
loads of apreq* files were visible in the temp directory, and then 
eventually exited and all the files disappeared.
