linux emulation: rt_sigtimedwait

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

So I'ved pkgsrc-ed IBM's proprietary Tivoli Storage Manager client, and, on 
6.0_BETA/amd64, I get:

 14453  14453 dsmc     CALL  mmap2(0,0x400000,7,0x20022,0xffffffff,0)
 14453  14453 dsmc     RET   mmap2 4212715520/0xfb18f000
 14453  14453 dsmc     CALL  mprotect(0xfb18f000,0x1000,0)
 14453  14453 dsmc     RET   mprotect 0
 14453  14453 dsmc     CALL

 14453  29374 dsmc     RET   set_robust_list 0
 14453  29374 dsmc     CALL

 14453  29374 dsmc     RET   time 1336570114/0x4faa7102
 14453  29374 dsmc     CALL  netbsd32_write(3,0xfb58a8d0,0x36)
 14453  29374 dsmc     GIO   fd 3 wrote 54 bytes
       "05/09/12   15:28:34 sigwait failed in pkWaitshutdown.\n"

I have no idea what rt_sigtimewait is. The only thing i do know is I have to 
get TSM working on this machine.

Any help greatly appreciated.
