Problems with Frescobaldi compiling .PDF file from Cygwin-installed version of LilyPond

[Robert Murdoch]

Hi, I've recently successfully installed the master branch of LilyPond 
through Cygwin. I did this because I lack the patience to wait for the 
next stable release where the repeat tie fiasco will be fixed.

That being said, Frescobaldi seems to be having trouble compiling a .PDF 
file through the Cygwin-installed LilyPond with the following message:

> Fork: child -1 forked process <number> died unexpectedly, retry 0, 
exit code 0xC0000135, errno 11
> warning: g_spawn_sync failed (0): gs: Failed to fork (Resource 
temporarily unavailable)

The strange thing is that when I run LilyPond from the command-line, it 
successfully compiles and generates a .PDF file with no problems.

What am I doing wrong besides, you know, being thoroughly impatient? 
Thanks for reading.
