True.
However I think qmail-send get concurrency[remote|local] back from
qmail-[r|l]spawn as a char that is then cast into an int.
char is 8 bit long.
Here is the code:
r = read(chanfdin[c],&ch,1);
while ((r == -1) && (errno == error_intr));
if (r < 1)
{ log1("alert: cannot start: hath the daemon spawn no fire?\n");
_exit(111)
; }
u = (unsigned int) (unsigned char) ch;
if (concurrency[c] > u) concurrency[c] = u;
numjobs += concurrency[c];
