It doesn't wait, it pretty much says "OK, Lets just drop the connection" and allows the FS to sort it out later.

PSORT(3) BSD Library Functions Manual PSORT(3)
NAME
psort, psort_b, psort_r -- parallel sort functions
SYNOPSIS
#include <stdlib.h>
void
psort(void *base, size_t nel, size_t width, int (*compar)(const void *, const void *));
void
psort_b(void *base, size_t nel, size_t width, int (^compar)(const void *, const void *));
void
psort_r(void *base, size_t nel, size_t width, void *thunk, int (*compar)(void *, const void *, const void *));
DESCRIPTION
The psort(), psort_b(), and psort_r() functions are parallel sort routines that are drop-in compatible with the corresponding qsort() func-
tion (see qsort(3) for a description of the arguments). On multiprocessor machines, multiple threads may be created to simultaneously per-
form the sort calculations, resulting in an overall faster sort result. Overhead in managing the threads limits the maximum speed improve-
ment to somewhat less that the number of processors available. For example, on a 4-processor machine, a typical sort on a large array might
result in 3.2 times faster sorting than a regular qsort().
RESTRICTIONS
Because of the multi-threaded nature of the sort, the comparison function is expected to perform its own synchronization that might be
required for data physically outside the two objects passed to the comparison function. However, no synchronization is required for the two
object themselves, unless some third party is also accessing those objects.
Additional memory is temporary allocated to deal with the parallel nature of the computation.
Because of the overhead of maintaining multiple threads, the psort() family of routines may choose to just call qsort(3) when there is no
advantage to parallelizing (for example, when the number of objects in the array is too small, or only one processor is available).
Like qsort(3), the sort is not stable.
RETURN VALUES
The psort(), psort_b() and psort_r() functions return no value.
