!!NOTES
getdtablesize(2) is implemented as a library function in DLL 4.4.1. This function returns __OPEN_MAX__ (set to 256 in Linux 2.0.23) if __OPEN_MAX__ was defined when the library was compiled. Otherwise, -1 is returned, and ''errno'' is set to [ENOSYS].
-A process under linux may open far more file descriptors than 256 however.
+A process under linux may open far more file descriptors than 256 however. To get even more file descriptors you have to tweak the system wide maximums with
