Here are the results from one of our linux servers:

# ./selecttest
selecttest: nsocks = 4093, TEST_FDSETSIZE = -1, FD_SETSIZE = 1024, 
sizeof fd_set = 128
created 4093 sockets, maxfd = 4095
FD_CLR test...OK
FD_SET test...OK
select test...OK

Based on the above, why do I get the "too many open file descriptors" 
error when I run 9.5.0-P1? Help my simple mind understand this. :) Does 
this mean that P2 will run as expected on this machine or will it give 
"too many open file descriptors" error also?
