Delay in job control

Hallo,

I looked a little more about the job control behaviour of netscape 3.0.

I start it from an rxvt. It displays the version screen. Typing suspend
("^Z") immediate returns to the prompt. I can repeat. No I open some remote
www page. Typing "^Z" and bringing it bach in the forground (fg)
repeatedly, after some cycles it takes long to get back to the command
prompt after the "^Z", over 20 seconds possibly. Causing a repaint event
immeateate returns the hanging suspends. I use tcsh, fvwm, but I think that
shouldn't matter as Linux uses preemtive multitasking.
With the hanging suspend, I get following /proc/<pid>/status:
Name: netscape
State: S (sleeping)
Pid: 500
PPid: 138
Uid: 503 503 503 503
Gid: 100 100 100 100
VmSize: 7600 kB
VmLck: 0 kB
VmRSS: 4760 kB
VmData: 1564 kB
VmStk: 24 kB
VmExe: 3668 kB
VmLib: 1452 kB
SigPnd: 00082000
SigBlk: 65686469
SigIgn: 80001080
SigCgt: 00016403
After a repaint event:
Name: netscape
State: T (stopped)
Pid: 500
PPid: 138
Uid: 503 503 503 503
Gid: 100 100 100 100
VmSize: 7600 kB
VmLck: 0 kB
VmRSS: 4760 kB
VmData: 1564 kB
VmStk: 24 kB
VmExe: 3668 kB
VmLib: 1452 kB
SigPnd: 00002000
SigBlk: 00000000
SigIgn: 80001080
SigCgt: 00016403

Any clues?
