I have found
this thread, which might help you and contains pointers to some additional sources.
I have never encountered a problem like the one you describe because there is a certain data type in C (pid_t) in the system header files. There should be no range problems if you use it. If someone wouldn't use it this would be extremely bad programming style and i wouldn't expect such a hack in a standard software (you mentioned Oracle).
Of course, nothing is really impossible, so maybe you have a point here, however unlikely. I'd appreciate it if you could tell us your findings once your investigation is completed.
I hope this helps.

ESIOP(4) BSD Kernel Interfaces Manual ESIOP(4)
NAME
esiop -- Enhanced Symbios Logic/NCR 53c8xx SCSI driver
SYNOPSIS
esiop* at pci? dev ? function ?
options SIOP_SYMLED
scsibus* at esiop?
DESCRIPTION
The esiop driver provides improved support over siop(4) for the Symbios Logic/NCR 53x8xx series of SCSI controller chips:
- 53c825 and 53c825a (Fast-Wide SCSI)
- 53c875 and 53c875j (Ultra-Wide SCSI)
- 53c876 (Dual Ultra-Wide SCSI)
- 53c885 (Ultra-Wide SCSI and Ethernet)
- 53c895 (Ultra2-Wide SCSI)
- 53c896 (PCI 64bit, dual Ultra2-Wide SCSI)
- 53c1010-33 (PCI 64bit, dual Ultra160 SCSI)
- 53c1510d (PCI 64bit, dual Ultra2-wide SCSI)
Older adapters are supported by the siop(4) driver.
The SIOP_SYMLED option causes the driver to report SCSI activity on the GPIO pin 1, which is connected to the activity LED on some adapters.
At this time only the 53c895 based Symbios and Tekram adapters are known to require this.
